If you have SQL 2012 x64 installed aren't there some files that are still x86? If so when you install SQL 2012 SP1, do you need to install both the x64 and x86 version of SP1?
I installed X64 version of SQL 2012 SP1, with no issues, but when i run the 32bit SQL 2012 SP1, it just hangs at sql server setup files are being installed on the system. I figured if it wasn't needed it would just pop up saying not applicable to the machine, but thats not happening, its just hanging on the sql server setup files are being installed.
Thanks
