Windows 7 compatible? in General Questions Posted August 16, 2009 Which Windows 7 build are you using? I'm running the only official W7 RC build - 7100 (with all current updates), and SAS 4.27.1002 Pro starts / runs / scans perfectly with no problems whatsoever. I'm running Win7 RC 7137 32-bit and, as I said, SAS doesn't work for me! 7137 is unofficial, no build since 7100 is. Later builds are only there (not officially in the public domain) to test a particular problem / issue that may have arisen. Consequently, as MS states, if you install a later 'test' build there may be other problems as a result.
