Thanks a lot for your reply. That means that I will not have to downgrade the pre-installed Win7 on my laptop to WinXP in order to install SAS 9.2. By SAS 9.2, do you mean SAS Enterprise or SAS Base/Foundations? Actually, I have been using only SAS Base/Foundations 9.1.3 in my studies. I have seen some PCs in my university installed with SAS, but all of them have SAS Enterprise, which I never have used before. Does SAS 9.2 still provide something similar to SAS Base 9.1.3?

Thanks a lot!
