Rick,
I checked with our folks internally and it looks like now, with the JVM support, we can support SAS 9.1.3 on Windows 2008. SAS 9.1.3 is a 32-bit app on Windows, so it runs in 32-bit mode if you use a 64-bit OS.
I saw your tech support track with this question. I will follow up with the tech support consultant to verify the information.
Also, note this advice for installation:
