Installer defines several properties at run time that are useful for defining conditions.
See Hardware Properties and Operating System Properties in the Windows Installer SDK
Help.
To set basic requirements, use the System Requirements page.

Enter the error message that appears if the destination computer doesn't meet
the condition. It should communicate to the end user why the installation

it precedes the LaunchCondtions action in the User Interface sequence. For silent
