Added Silverlight 3.
This is a silent installer for Microsoft Silverlight, a plugin for rich interactive web content, in some extent similar to Macromedia Flash Player.
== Silverlight 2 ==
<source lang="xml">
Silverlight install sometimes (always for some) exits with strange error codes (and says that it has done a rollback), yet the plugin is working fine after such fiasco.
== Silverlight 3 ==
<source lang="xml">
<package id="silverlight3" name="SilverLight 3 with auto-update check disabled" revision="1" reboot="false" priority="0">
<check type='file' condition='versionequalto' path='%PROGRAMFILES%\Microsoft Silverlight\sllauncher.exe' value='3.0.40624.0' />
<install cmd='"%SOFTWARE%\silverlight3\SilverLight.exe" /q /noupdate' />
<upgrade cmd='"%SOFTWARE%\silverlight3\SilverLight.exe" /q /noupdate' />
<remove cmd='MsiExec.exe /X{89F4137D-6C26-4A84-BDB8-2E5A4BB71E00}' />
</package>
</source>
Please notice how check has to be performed on an executable since the uninstall string seems to always be "Microsoft Silverlight" despite the version. Also notice that uninstallation GUID seems to always be {89F4137D-6C26-4A84-BDB8-2E5A4BB71E00} despite the version.
Some documentation on Silveright installation switches: http://blogs.technet.com/extreme/archive/2009/04/02/silverlight-installation-switches.aspx.
The "/noupdate" installation switch seems to set the "HKEY_LOCAL_MACHINE\Software\Microsoft\Silverlight" "UpdateMode" to DWORD value "2".
