Parameters

Attribute

Type

Description

Required

id

string

Identifier of the merge module required

True

language

string

Numeric language ID of the merge module in ExcludedID. The ExcludedLanguage column can specify the language ID for a single language, such as 1033 for U.S. English, or specify the language ID for a language group, such as 9 for any English. The ExcludedLanguage column can accept negative language IDs. The meaning of the value in the ExcludedLanguage column is as follows.

> 0	Exclude the language IDs specified by ExcludedLanguage.
= 0	Exclude no language IDs.
< 0	Exclude all language IDs except those specified by ExcludedLanguage.

True

minversion

string

Minimum version excluded from a range. If ommitted, all versions before maxversion are excluded. If both minversion and maxversion are ommitted there is no exclusion based on version.

False

maxversion

string

Maximum version excluded from a range. If ommitted, all versions after minversion are excluded. If both minversion and maxversion are ommitted there is no exclusion based on version.

False

Examples

Exclude the all NAnt merge modules created before version 0.85.0

<moduleexclusions>
    <exclusion id="NAnt_MergeModule.2D2FB50C_DADF_4813_8932_8EF1E8CB8E80" language="0" maxversion="0.85.0" />
</moduleexclusions>

Represents the an element based on a schema definition.

Used to modify the sequence of tasks/events that execute during the overall installation process.

Parameters

Attribute Type Description Required

type

msi:MSISequenceTable

Valid inputs:

installexecute represents ModuleInstallExecuteSequence Table.
installui represents ModuleInstallUISequence Table
adminexecute represents ModuleAdminExecuteSequence Table
adminui represents ModuleAdminUISequence Table
advtexecute represents ModuleAdvtUISequence Table

True

action string Action to insert into sequence. Refers to one of the installer standard actions, or an entry in the merge module's CustomAction table or Dialog table.

If a standard action is used in the Action column of a merge module sequence table, the BaseAction and After attributes must be ommitted. True

sequence int The sequence number of a standard action. If a custom action or dialog is entered into the Action column of this row, this attribute must be ommitted

When using standard actions in merge module sequence tables, the value in the Sequence column should be the recommended action sequence number. If the sequence number in the merge module differs from that for the same action in the .msi file sequence table, the merge tool uses the sequence number from the .msi file. See the suggested sequences in Using a Sequence Table for the recommended sequence numbers of standard actions. False

baseaction string Can contain a standard action, a custom action specified in the merge module's custom action table, or a dialog specified in the module's dialog table. Is a key into the Action column of this table. It cannot be a foreign key into another merge table or table in the .msi file. This means that every standard action, custom action, or dialog listed in the BaseAction column must also be listed in the Action column of another record in this table. False

after

bool

Boolean for whether Action comes before or after BaseAction

Value	Description
True	Action to come after BaseAction
False	Action to come before BaseAction

False

condition string A conditional statement that indicates if the action is be executed. False

Represents the an element based on a schema definition.

If a table in the merge module is listed in the ModuleIgnoreTable table, it is not merged into the .msi file. If the table already exists in the .msi file, it is not modified by the merge. The tables in the ModuleIgnoreTable can therefore contain data that is unneeded after the merge.

More information is available here.

Parameters

Attribute	Type	Description	Required
table	string	Name of the table in the merge module that is not to be merged into the .msi file.	True

Examples

Ensure the module is compatible for users who have versions of Mergemod.dll earlier than 2.0

<moduleignoretables>
    <table name="ModuleConfiguration" />
    <table name="ModuleSubstitution" />
    <table name="_ModuleConfigurationGroup" />
</moduleignoretables>

Represents the an element based on a schema definition.

The ModuleSubstitution table specifies the configurable fields of a module database and provides a template for the configuration of each field. The user or merge tool may query this table to determine what configuration operations are to take place. This table is not merged into the target database.

More information is available here.

Parameters

Attribute	Type	Description	Required
table	string	Name of the table being modified in the module database.	True
row	string	Specifies the primary keys of the target row in the table named in the Table column. Multiple primary keys are separated by semicolons. Target rows are selected for modification before any changes are made to the target table. If one record in the ModuleSubstitution table changes the primary key field of a target row, other records in the ModuleSubstitution table are applied based on the original primary key data, not the resulting of primary key substitutions. The order of row substitution is undefined. Values in this column are always in CMSM special format. A literal semicolon (';') or equal sign ('=') can be added by prefixing the character with a backslash. '\'. A null value for a key is signified by a null, a leading semicolon, two consecutive semicolons, or a trailing semicolon, depending on whether the null value is a sole, first, middle, or final key column value.	True
column	string	Specifies the target column in the row named in the Row column. If multiple rows in the ModuleSubstitution table change different columns of the same target row, all the column substitutions are performed before the modified row is inserted into the database. The order of column substitution is undefined.	True
value	string	Contains a string that provides a formatting template for the data being substituted into the target field specified by Table, Row, and Column. When a substitution string of the form [=ItemA] is encountered, the string, including the bracket characters, is replaced by the value for the configurable "ItemA." The configurable item "ItemA" is specified in the Name column of the ModuleConfiguration table and its value is provided by the merge tool. If the merge tool declines to provide a value for any item in a replacement string, the default value specified in the DefaultValue column of the ModuleConfiguration Table is substituted. If a string references an item not in the ModuleConfiguration table, the merge fails. This column uses CMSM special format. A literal semicolon (';') or equals sign ('=') can be added to the table by prefixing the character with a backslash. '\'. The Value field may contain multiple substitution strings. For example, the configuration of items "Food1" and "Food2" in the string: "[=Food1] is good, but [=Food2] is better because [=Food2] is more nutritious." Replacement strings must not be nested. The template "[=AB[=CDE]]" is invalid. If the Value field evaluates to null, and the target field is not nullable, the merge fails and an error object of type msmErrorBadNullSubstitution is created and added to the error list. For details, see the error types described in get_Type Function. If the Value field evaluates to the null GUID: {00000000-0000-0000-0000-000000000000}, the null GUID is replaced by the name of the feature before the row is merged into the module. For details, see Referencing Features in Merge Modules. The template in the Value field is evaluated before being inserted into the target field. Substitution into a row is done before replacing any features. If the Value column evaluates to a string of only integer characters (with an optional + or -), the string is converted into an integer before being substituted into an target field of the Integer Format Type. If the template evaluates to a string that does not consist only of integer characters (and an optional + or -) the result cannot be substituted into an integer target field. Attempting to insert a non-integer into an integer field causes the merge to fail and adds a msmErrorBadSubstitutionType error object to the error list. If the target column specified in the Table and Column fields is a Text Format Type, and evaluation of the Value field results in an Integer Format Type, a decimal representation of the number is inserted into the target text field. If the target field is an Integer Format Type, and the Value field consists of a non-delimited list of items in Bitfield Format, the value in the target field is combined using the bitwise AND operator with the inverse of the bitwise OR of all of the mask values from the items, then combined using the bitwise OR operator with each of the integer or bitfield items when masked by their corresponding mask values. Essentially, this explicitly sets the bits from the properties to the provided values but leaves all other bits in the cell alone. If the Value field evaluates to a Key Format Type, and is a key into a table that uses multiple primary keys, the item name may be followed by a semicolon and an integer value that indicates the 1-based index into the set of values that together make a primary key. If no integer is specified, the value 1 is used. For example, the Control table has two primary key columns, Dialog_ and Control. The value of an item "Item1" that is a key into the Control table will be of the form "DialogName;ControlName", where DialogName is the value in the Dialog_ table and ControlName is the value in the Control column. To substitute just ControlName, the substitution string [=Item1;2] should be used.	False

Parameters

Attribute

Type

Description

Required

name

string

Name of the configurable item. This name is referenced in the formatting template in the Value column of the ModuleSubstitution table.

True

format

msi:MSMModuleConfigurationFormat

Specifies the format of the data being changed

text
key
integer
bitfield

True

type

string

Specifies the type for the data being changed. This type is used to provide a context for any user-interface and is not used in the merge process. The valid values for this depend on the value in the Format attribute.

False

contextdata

string

Specifies a semantic context for the requested data. The type is used to provide a context for any user-interface and is not used in the merge process. The valid values for this column depend on the values in the Format and Type attributes.

False

defaultvalue

string

Specifies a default value for the item in this record if the merge tool declines to provide a value. This value must have the format, type, and context of the item. If this is a "Key" format item, the foreign key must be a valid key into the tables of the module. Null may be a valid value for this column depending on the item. For "Key" format items, this value is in CMSM special format. For all other types, the value is treated literally.

Module authors must ensure that the module is valid in its default state. This ensures that versions of Mergemod.dll earlier than version 2.0 can still use the module in its default state.

False

attr

int

Bit field containing attributes for this configurable item. Null is equivalent to 0.

Value	Description
1	This attribute only applies to records that list a foreign key to a module table in their DefaultValue field.
2	When this attribute is set, null is not a valid response for this item. This attribute has no effect for Integer Format Types or Bitfield Format Types.

False

displayname

string

Provides a short description of this item that the authoring tool may use in the user interface. This column may not be localized. Set this column to null to have the module is request that the authoring tool not expose this property in the UI.

False

description

string

Provides a description of this item that the authoring tool may use in UI elements. This string may be localized by the module's language transform.

False

helplocation

string

Provides either the name of a help file (without the .chm extension) or a semicolon delimited list of help namespaces. This can be ommitted if no help is available.

False

helpkeyword

string

Provides a keyword into the help file or namespace from the HelpLocation column. The interpretation of this keyword depends on the HelpLocation attribute.

Represents the an element based on a schema definition.

Used to modify the environment variables of the target computer at runtime.

Parameters

Attribute

Type

Description

Required

name

string

The localizable name of the environment variable. The key values are written or removed depending upon which of the characters in the following table are prefixed to the name. There is no effect in the ordering of the symbols used in a prefix.

Prefix	Description
=	Create the environment variable if it does not exist, and then set it during installation. If the environment variable exists, set it during the installation.
+	Create the environment variable if it does not exist, then set it during installation. This has no effect on the value of the environment variable if it already exists.
-	Remove the environment variable when the component is removed. This symbol can be combined with any prefix.
!	Remove the environment variable during an installation. The installer only removes an environment variable during an installation if the name and value of the variable match the entries in the Name and Value fields of the Environment table. If you want to remove an environment variable, regardless of its value, use the '!' syntax, and leave the Value field empty.
*	This prefix is used with Microsoft® Windows® NT/Windows® 2000 to indicate that the name refers to a system environment variable. If no asterisk is present, the installer writes the variable to the user's environment. Microsoft Windows 95/98 ignores the asterisk and add the environment variable to autoexec.bat. This symbol can be combined with any prefix. A package that is used for per-machine installations should write environment variables to the machine's environment by including * in the Name column. For more information, see http://msdn.microsoft.com/library/en-us/msi/setup/environment_table.asp
=-	The environment variable is set on install and removed on uninstall. This is the usual behavior.
!-	Removes an environment variable during an install or uninstall.

More information can be found here: http://msdn.microsoft.com/library/en-us/msi/setup/environment_table.asp

True

append

string

Localizable value that is to be set as a formatted string

True

component

string

Refrence to a component. Allows the variabled to be modified when the component is un/installed.

True

Examples

Append the installation path to the user PATH variable.

<environment>
    <variable name="PATH" append="'[TARGETDIR]'" component="C__MainFiles" />
</environment>

Represents the an element based on a schema definition.

Groups sets of files into named sets, these can be used to install and perform operations on a set of files as one entity.

Parameters

Attribute Type Description Required

name string A name used to refer to the component. True

id string A string GUID unique to this component, version, and language.

Note that the letters of these GUIDs must be uppercase. Utilities such as GUIDGEN can generate GUIDs containing lowercase letters. The lowercase letters must be changed to uppercase to make these valid component code GUIDs. True

attr

int

This column contains a bit flag that specifies options for remote execution. Add the indicated bit to the total value in the column to include an option.

Value	Description
0	Component cannot be run from source. Set this bit for all components belonging to a feature to prevent the feature from being run-from-network or run-from-source. Note that if a feature has no components, the feature always shows run-from-source and run-from-my-computer as valid options.
1	Component can only be run from source. Set this bit for all components belonging to a feature to prevent the feature from being run-from-my-computer. Note that if a feature has no components, the feature always shows run-from-source and run-from-my-computer as valid options.
2	Component can run locally or from source.
4	If this bit is set, the value in the key element is used as a key into the Registry table. If the Value field of the corresponding record in the Registry table is null, the Name field in that record must not contain "+", "-", or "*". For more information, see the description of the Name field in Registry table. Setting this bit is recommended for registry entries written to the HKCU hive. This ensures the installer writes the necessary HKCU registry entries when there are multiple users on the same machine.
16	If this bit is set, the installer does not remove the component during an uninstall. The installer registers an extra system client for the component in the Windows Installer registry settings.
32	If this bit is set, the value in the KeyPath column is a key into the ODBCDataSource table.
64	If this bit is set, the installer reevaluates the value of the statement in the Condition column upon a reinstall. If the value was previously False and has changed to True, the installer installs the component. If the value was previously True and has changed to False, the installer removes the component even if the component has other products as clients. This bit should only be set for transitive components. See Using Transitive Components.
128	If this bit is set, the installer does not install or reinstall the component if a key path file or a key path registry entry for the component already exists. The application does register itself as a client of the component. Use this flag only for components that are being registered by the Registry table.
256	Set this bit to mark this as a 64-bit component. This attribute facilitates the installation of packages that include both 32-bit and 64-bit components. If this bit is not set, the component is registered as a 32-bit component.

True

directory string Refrence to a directory. Defines the directory location for where the files assigned to the component are to be placed. True

feature string Refrence to a feature. Maps a feature to the component. Used to determine if the component is to be installed or not. True

condition string A conditional statement that can control whether a component is installed. If the condition is null or evaluates to true, then the component is enabled. If the condition evaluates to False, then the component is disabled and is not installed. False

fileattr

int

Integer containing bit flags representing file attributes.

The following table shows the definition of the bit field.

Value	Description
1	Read-Only
2	Hidden
4	System
512	The file is vital for the proper operation of the component to which it belongs
1024	The file contains a valid checksum. A checksum is required to repair a file that has become corrupted.
4096	This bit must only be added by a patch and if the file is being added by the patch.
8192	The file's source type is uncompressed. If set, ignore the Word Count Summary Property. If neither msidbFileAttributesNoncompressed or msidbFileAttributesCompressed are set, the compression state of the file is specified by the Word Count Summary Property. Do not set both msidbFileAttributesNoncompressed and msidbFileAttributesCompressed.
16384	The file's source type is compressed. If set, ignore the Word Count Summary Property. If neither msidbFileAttributesNoncompressed or msidbFileAttributesCompressed are set, the compression state of the file is specified by the Word Count Summary Property. Do not set both msidbFileAttributesNoncompressed and msidbFileAttributesCompressed.

False

checkinterop bool Used to determine if file(s) in the fileset are interop file(s). If true, extra information will be added in the install package to register each interop file. If false, the file(s) will not be not be checked and the extra registration information will not be added to the msi. False

installassembliestogac bool Used to determine if assemblies should be installed to the Global Assembly Cache. If true, all assemblies in the fileset will be added to the GAC. If false, the assemblies will be installed to the specified directory (as a normal file would). Note: If an assembly is specified to be installed into the GAC, it will not also be installed to the directory specified. False

keepsubdirs bool Used to determine if directories in the fileset should be built. If true, all subdirectories of the fileset basedir will be built. If false the directories structure will be flattened. The default is false. False

More information here: http://msdn.microsoft.com/library/en-us/msi/setup/dialog_style_bits.asp

True

title

string

A localizable text string specifying the title to be displayed in the title bar of the dialog box.

True

firstcontrol

string

An external key to the second column of the Control table. Combining this field with the Dialog field identifies a unique control in the Control table. This defines the control that takes the focus when the dialog box is created. This column is ignored in an Error dialog box.

Because static text cannot take the focus, a Text control that describes an Edit, PathEdit, ListView, ComboBox or VolumeSelectCombo control must be made the first control in the dialog box to ensure compatibility with screen readers.

True

defaultcontrol

string

An external key to the second column of the Control table. Combining this field with the Dialog field results in a primary key into the Control table that defines the default control. Hitting the Return key is equivalent to clicking on the default control. If this column is left blank, then there is no default control. This column is ignored in the Error dialog box.

True

cancelcontrol

string

An external key to the second column of the Control table. Combining this field with the Dialog field results in a primary key of the Control table that defines the cancel control. Hitting the ESC key or clicking the Close button in the dialog box is equivalent to clicking on the cancel control. This column is ignored in an Error dialog box.

The cancel control is hidden during rollback or the removal of backed up files. The protected UI handler hides the control upon receiving a INSTALLMESSAGE_COMMONDATA message.

True

Examples

Add a web folder dialog:

<dialogs>
    <dialog name="WebFolderDlg" hcenter="50" vcenter="50" width="370" height="270" attr="39" title="[ProductName] [Setup]" firstcontrol="Next" defaultcontrol="Next" cancelcontrol="Cancel" />

attr int A 32-bit word that specifies the bit flags to be applied to this control. This must be a non-negative number, and the allowed values depend upon the type of control.For a list of all control attributes, and the value to enter in this field, see Control Attributes. True

property string The name of a defined property to be linked to this control. Radio button, list box, and combo box values are tied into a group by being linked to the same property. This column is required for active controls and is ignored by static controls. False

text string A localizable string used to set the initial text contained in a control. The string can also contain embedded properties. False

nextcontrol string The name of another control on the same dialog box. If the focus in the dialog box is on the control in the Control column, hitting the tab key moves the focus to the control listed here. Therefore this is used to specify the tab order of the controls on the dialog box. The links between the controls must form a closed cycle. Some controls, such as static text controls, can be left out of the cycle. In that case, this field may be left blank. False

help string Optional, localizable text strings that are used with the Help button. The string is divided into two parts by a separator character (|). The first part of the string is used as ToolTip text. This text is used by screen readers for controls that contain a picture. The second part of the string is reserved for future use. The separator character is required even if only one of the two kinds of text is present. False

remove bool If true, the control is removed. If false, the control is added. False

Parameters

Attribute	Type	Description	Required
component	string	Refrence to a component. The component that controls the installation of the registry value.	True
root	msi:MSIRegistryKeyRoot	Valid input: `dependent` - If this is a per-user installation, the registry value is written under HKEY_CURRENT_USER. If this is a per-machine installation, the registry value is written under HKEY_LOCAL_MACHINE. Note that a per-machine installation is specified by setting the ALLUSERS property to 1. `machine` represents HKEY_LOCAL_MACHINE `classes` represents HKEY_CLASSES_ROOT `user` represents HKEY_CURRENT_USER `users` represents HKEY_USERS	True
path	string	Registry key.	True

Nested Elements:

<value>

Attribute

Type

Description

Required

name

string

The registry value name (localizable). If this is Null, then the data entered into the Value column are written to the default registry key.

If the Value column is Null, then the strings shown in the following table in the Name column have special significance.

String	Description
+	The key is to be created, if absent, when the component is installed.
-	The key is to be deleted, if present, with all of its values and subkeys, when the component is uninstalled.
*	The key is to be created, if absent, when the component is installed. Additionally, the key is to be deleted, if present, with all of its values and subkeys, when the component is uninstalled.

False

value

string

The localizable registry value. The field is Formatted. If the value is attached to one of the following prefixes (i.e. #%value) then the value is interpreted as described in the table. Note that each prefix begins with a number sign (#). If the value begins with two or more consecutive number signs (#), the first # is ignored and value is interpreted and stored as a string.

Prefix	Description
#x	The value is interpreted and stored as a hexadecimal value (REG_BINARY).
#%	The value is interpreted and stored as an expandable string (REG_EXPAND_SZ).
#	The value is interpreted and stored as an integer (REG_DWORD).

If the value contains the sequence tilde [~], then the value is interpreted as a Null-delimited list of strings (REG_MULTI_SZ). For example, to specify a list containing the three strings a, b and c, use "a[~]b[~]c."
The sequence [~] within the value separates the individual strings and is interpreted and stored as a Null character.
If a [~] precedes the string list, the strings are to be appended to any existing registry value strings. If an appending string already occurs in the registry value, the original occurrence of the string is removed.
If a [~] follows the end of the string list, the strings are to be prepended to any existing registry value strings. If a prepending string already occurs in the registry value, the original occurrence of the string is removed.
If a [~] is at both the beginning and the end or at neither the beginning nor the end of the string list, the strings are to replace any existing registry value strings.
Otherwise, the value is interpreted and stored as a string (REG_SZ).

False

dword

string

A dword value to input, if the value attribute is null. This removes the requirement of adding "#" before the value.

False

id

string

Primary key used to identify a registry record.

False

</value>
