### Parameters

Attribute | Type | Description | Required
--- | --- | --- | ---
background | string | A .bmp (bitmap) file 495x315 pixels in size that will be displayed as the background image of the installation user interface. | False
banner | string | A .bmp (bitmap) file 495x60 pixels in size that will be displayed as the banner (top) image of the installation user interface. | False
license | string | An .rtf (rich text format) file containing the license agreement for your software. The contents of this file will be displayed to the user when setup runs and must be accepted to continue. | False
output | string | The name of the file that will be generated when the task completes execution (eg. MyInstall.msi or MyMergeModule.msm). | True
sourcedir | string | A directory relative to the NAnt script in which the msi task resides from which to retrieve files that will be installed by the msi database. All files that will be included in your installation need to be located directly within or in subdirectories of this directory. | True
debug | bool | Causes the generated msi database file to contain debug messages for errors created by inconsistencies in creation of the database. This makes the file slightly larger and should be avoided when generating a production release of your software. | False
errortemplate | string | A .mst file to use as the starting database containing strings displayed to the user when errors occur during installation. A .mst template is included with the msi task, you only need to supply this value if you want to override the default error template and cannot perform something through the features of the msi task. | False
failonerror | bool | Determines if task failure stops the build, or is just reported. The default is true. | False
if | bool | If true then the task will be executed; otherwise, skipped. The default is true. | False
template | string | A installer file to use as the starting database in which all files and entries will be made, and then copied to the filename specified by the output parameter. Install templates are included with the install tasks, you only need to supply this value if you want to override the default template. | False
unless | bool | Opposite of `if`. If false then the task will be executed; otherwise, skipped. The default is false. | False
verbose | bool | Determines whether the task should report detailed build log messages. The default is false. | False

### Nested Elements:

#### <features>

Groups sets of components into named sets, these can be used to layout the tree control that allows users to select and deselect features of your software product when a custom installation is selected at runtime.

### Parameters

Attribute | Type | Description | Required
--- | --- | --- | ---
name | string | A name used to refer to the feature. | True
display | int | The number in this field specifies the order in which the feature is to be displayed in the user interface. The value also determines if the feature is initially displayed expanded or collapsed. If the value is null or zero, the record is not displayed. If the value is odd, the feature node is expanded initially. If the value is even, the feature node is collapsed initially. | True
title | string | Short string of text identifying the feature. This string is listed as an item by the SelectionTree control of the Selection Dialog. | False
typical | bool | Determines if the feature should be included in a "typical" install. This is useful for when the user selects to just install the typical features. | False
directory | string | Refrence to a directory. Specify a corresponding directory to go with the feature. | False
attr | int | Any combination of the following:
Value | Description
--- | ---
0 | Components of this feature that are not marked for installation from source are installed locally.
1 | Components of this feature not marked for local installation are installed to run from the source CD-ROM or server.
2 | Set this attribute and the state of the feature is the same as the state of the feature's parent.
4 | Set this attribute and the feature state is Advertise.
8 | Note that this bit works only with features that are listed by the ADVERTISE property. Set this attribute to prevent the feature from being advertised.
16 | Set this attribute and the user interface does not display an option to change the feature state to Absent. Setting this attribute forces the feature to the installation state, whether or not the feature is visible in the UI.
32 | Set this attribute and advertising is disabled for the feature if the operating system shell does not support Windows Installer descriptors.
More information found here: http://msdn.microsoft.com/library/en-us/msi/setup/feature_table.asp | False

### Nested Elements:

#### <feature>

Nested feature elements are supported.

#### </feature>

#### <description>

Longer string of text describing the feature. This localizable string is displayed by the Text control of the Selection Dialog.

#### </description>

#### <conditions>

#### <condition>

Attribute | Type | Description | Required
--- | --- | --- | ---
expression | string | If this conditional expression evaluates to TRUE, then the Level column in the Feature table is set to the conditional install level. The expression in the Condition column should not contain reference to the installed state of any feature or component. This is because the expressions in the Condition column are evaluated before the installer evaluates the installed states of features and components. Any expression in the Condition table that attempts to check the installed state of a feature or component always evaluates to false. For information on the syntax of conditional statements, see Conditional Statement Syntax. | True
level | int | The installer sets the install level of this feature to the level specified in this column if the expression in the Condition column evaluates to TRUE. Set this value to 0 to have the component not install if the condition is not met. For any installation, there is a defined install level, which is an integral value from 1 to 32,767. The initial value is determined by the InstallLevel property, which is set in the Property table. A feature is installed only if the feature level value is less than or equal to the current install level. The user interface can be authored such that once the installation is initialized, the installer allows the user to modify the install level of any feature in the Feature table. For example, an author can define install level values that represent specific installation options, such as Complete, Typical, or Minimum, and then create a dialog box that uses SetInstallLevel ControlEvents to enable the user to select one of these states. Depending on the state the user selects, the dialog box sets the install level property to the corresponding value. If the author assigns Typical a level of 100 and the user selects Typical, only those features with a level of 100 or less are installed. In addition, the Custom option could lead to another dialog box containing a Selection Tree control. The Selection Tree would then allow the user to individually change whether each feature is installed. | True

#### </condition>

#### </conditions>

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.

#### </environment>

#### <components>

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

1 | Visible
2 | Modal
4 | Minimize
8 | SysModal
16 | KeepModeless
32 | TrackDiskSpace
64 | UseCustomPalette
128 | RTLRO
256 | RightAligned
512 | LeftScroll
896 | BiDi
65536 | Error
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" />

More information found here: http://msdn.microsoft.com/library/en-us/msi/setup/controls.asp | True
x | int | Horizontal coordinate of the upper-left corner of the rectangular boundary of the control. This must be a non-negative number. | True
y | int | Vertical coordinate of the upper-left corner of the rectangular boundary of the control. This must be a non-negative number. | True
width | int | Width of the rectangular boundary of the control. This must be a non-negative number. | True
height | int | Height of the rectangular boundary of the control. This must be a non-negative number. | True
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

#### <registry>

Makes modifications to the Windows Registry of the target computer at runtime.

### 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>

Specifies the registry value to add to the target machine.

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>

2 | AccessWrite | Users are allowed to upload files and their associated properties to the enabled directory on your server or to change content in a Write-enabled file. Write can be implemented only with a browser that supports the PUT feature of the HTTP 1.1 protocol standard.
4 | AccessExecute | The file or the contents of the folder may be executed, regardless of file type.
8 | AccessSSL | File access requires SSL file permission processing, with or without a client certificate.
16 | AccessSource | Users are allowed to access source code if either Read or Write permissions are set. Source code includes scripts in Microsoft ® Active Server Pages (ASP) applications.
32 | AccessSSLNegotiateCert | SSL file access processing requests a certificate from the client. A value of false indicates that access continues if the client does not have a certificate. Some versions of Internet Explorer will close the connection if the server requests a certificate and a certificate is not available (even if AccessSSLRequireCert is also set to true).
64 | AccessSSLRequireCert | SSL file access processing requests a certificate from the client. If the client provides no certificate, the connection is closed. AccessSSLNegotiateCert must also be set to true when using AccessSSLRequireCert.
128 | AccessSSLMapCert | SSL file permission processing maps a client certificate to a Microsoft Windows ® operating system user-account. The AccessSSLNegotiateCert property must also be set to true for the mapping to occur.
256 | AccessSSL128 | File access requires SSL file permission processing with a minimum key size of 128 bits, with or without a client certificate.

1024 | AccessNoRemoteWrite | Remote requests to create or change files are denied; only requests from the same computer as the IIS server succeed if the AccessWrite property is set to true. You cannot set AccessNoRemoteWrite to false to enable remote requests, and set AccessWrite to false to disable local requests.
4096 | AccessNoRemoteRead | Remote requests to view files are denied; only requests from the same computer as the IIS server succeed if the AccessRead property is set to true.
