Hi Chris,
It appears to be some confusion still as to whether or not SAS 9.1.3 SP4 can be installed on a Windows 2008 Server 64-bit.
There is documentation that SAS 9.1.3 SP4 can only be installed on a Windows 2008 Server 32-bit server ...

........ and there are release notes saying you can install it on a Windows 2008 Server 64-bit.

I've talked to a few Tech Support people and they both were not aware that SAS supports SAS 9.1.3 SP4 on a a Windows 2008 Server 64-bit. I have personally installed SAS 9.1.3 SP4 on 64-bit hardware (Windows 2003 server) and I can confirm that as I was unable to do so on a Windows 2008 Server 64-bit and receiving the 64-bit error message halting my installation. Can we clear the air here. I asked SAS Tech Support what the officail statement is regarding this and they both replied "SAS 9.1.3 SP4 is not supported on a Windows 2008 Server 64-bit". True or false?
Thanks
