You can use the GetVersion plug-in to detect this.

I guess, if you know already that you're under Vista, you could just compare $PROGRAMFILES32 and $PROGRAMFILES64

If they are different, you're under a 64-bits OS

In x64.nsh you have ${If} ${RunningX64}

I found this thread while searching for the same - but not for Vista only. Is there a more general way in NSIS to find the bitness of the OS?

If not for any OS, perhaps for Windows XP, Vista and Windows 7?

Thanks.
