Operating System Property Values (2k8 R2 vs Win7)

Question

I'm looking at the Microsoft article for Operating System Property Values and it seems that both Windows Server 2008 R2 and Windows 7 have a VersionNT value of 601. I see in the comments on the article that you should use MsiNTProductType to differentiate the two.

So if I wanted to only allow server 2008 R2 installations (and not Windows 7), then would this be the correct condition:

MsiNTProductType > 1 AND VersionNT = 601

This would allow me any Windows 2008 R2 PC that is a domain controller or a server (Which Windows 7 is not?)

Answer 1

I just built a MSI installer with that launch condition and that will indeed work just fine.

Answer 2

To prevent failing in the future you should use:

MsiNTProductType > 1 AND VersionNT >= 601

This means your condition will still install on yet-to-be-developed versions of Windows Server. Note that >= is required if you are putting your software forward for logo testing.
