How to check the system is Windows 7 or Windows Server 2008 R2 in Wix Installer?

Question

I am working on a windows installer project. And now I only want the software only can be installed on Windows 7 or Windows Server 2008 R2 system, I tried to use this:

<Condition Message='Windows Server 2008 R2 or Windows 7 is required'>(VersionNT = 600 AND ServicePackLevel = 1) OR VersionNT = 601 </Condition>

but it can still be installed on Windows Vista. Please help!

Thank you!

Just check for VersionNT 601 or newer, Windows 7 and Server 2008 R2 both have the same value.

<Condition Message="Win7 or 2008 R2 required"><![CDATA[Installed OR VersionNT >= 601]]></Condition>
