I am running Vista Ultimate SP1 x64, latest updates included. I have not been able to install SQL Server 2000's Enterprise Manager on this system. I have MSDN Developer x64 edition and it states that it is not compatible with this version of windows and tells me to verify if its x86 or x64.
I had to install it on an XP box and then RDP to that system but that can be a hassle just to get to EM. I dont need the DB Server portion, just Enterprise Manager.
