## XSIApplication.InstallAddon

### Description

Installs an .xsiaddon file in Softimage. An add-on file is a set of customized items (like layout, toolbar, preset, etc.) that are packaged in a single file. You can package, install and uninstall an add-on through the Softimage object model.

### C# Syntax

    XSIApplication.InstallAddon( String in_bszFileName, siInstallationPath in_eInstallDir, Boolean in_bBatch );

### Scripting Syntax

    XSIApplication.InstallAddon( FileName, [InstallDir], [NoUI] );

### Parameters

Parameter | Type | Description
--- | --- | ---
FileName | String | File path of the add-on file to install.
InstallDir | siInstallationPath | Destination directory, where the add-on is installed. siUserAddonPath and siWorkgroupAddonPath are the recommended values. If siUnknownPath is specified then the add-on will be installed at the default location specified inside the add-on file. Note: In the case of multiple workgroups, this method always installs to the first workgroup in the list. Default Value: siUnknownPath
NoUI | Boolean | Use this optional parameter to avoid displaying the warning message boxes that are shown during the installation of certain addons. This is automatically set when running Softimage in batch mode. Default Value: false

### Examples

#### JScript Example

    //
    // This example demonstrates how to install an add-on package.
    //
    // Get the first available workgroup as the add-on destination
    var sPath = Application.InstallationPath( siWorkgroupPath );
    if ( !sPath ) {
            // If the workgroup doesn't already exist, then add it
            var tmppath = XSIUtils.BuildPath( Application.InstallationPath(siUserPath), "TempWorkgrp" );
            var fso = new ActiveXObject( "Scripting.FileSystemObject" );
            if ( !fso.FolderExists(tmppath) ) { fso.CreateFolder(tmppath); }
            Application.AddWorkgroup( tmppath );
            sPath = Application.InstallationPath( siWorkgroupPath );
    }
    var sHTMLName = makeHTMLPage();
    // Create the add-on package object
    var oAddOn = Application.CreateAddon();
    // Add the HTML page to the add-on package
    oAddOn.AddOtherItem( sHTMLName );
    // Save the package in the Addons directory
    sPath = XSIUtils.BuildPath( sPath, "Addons" );
    XSIUtils.EnsureFolderExists( sPath );
    var sAddOnFileName = XSIUtils.BuildPath( sPath, "myHelpPkg.xsiaddon" );
    oAddOn.Save( sAddOnFileName );
    Application.LogMessage( "Created add-on file: " + sAddOnFileName );
    // Install the add-on package containing the HTML page
    Application.InstallAddOn( sAddOnFileName, siWorkgroupAddonPath );
    // Comment out the following line if you want to see the add-on file
    // (you will have to uninstall the add-on manually):
    Application.UnInstallAddon( sAddOnFileName );
    // **********************************
    // This function just provide the means to remove the details of
    // creating the HTML page.
    function makeHTMLPage()
    {
            // Build the filename & path
            var sUserPath = Application.InstallationPath( siUserPath );
            var sHelpFileName = XSIUtils.BuildPath( sUserPath, "Data", "HelpMe.html" );
            // Create a standard hello world script file
            var fso = new ActiveXObject( "Scripting.FileSystemObject" );
            var fHWFile = fso.CreateTextFile( sHelpFileName );
            fHWFile.WriteLine( "<html>" );
            fHWFile.WriteLine( "<head>" );
            fHWFile.WriteLine( "\t<title>Help Page for Testing Add-ons</title>" );
            fHWFile.WriteLine( "</head>" );
            fHWFile.WriteLine( "<body>" );
            fHWFile.WriteLine( "\n<p>Help! I'm trapped inside this HTML code!</p>" );
            fHWFile.WriteLine( "</body>" );
            fHWFile.WriteLine( "</html>" );
            fHWFile.Close();
            // Return the name of the new html page
            return sHelpFileName;
    }
