The key when installing such things is to make sure the computer is clean and functioning well.. Cleanout all the junk files, temporary internet files, and Temp folders. Uninstall any programs you don't use.. Run your antivirus and antispyware scans to be sure everything's clean. And once that's done, run a Defrag and Chkdsk to optimize the drive.
In addition, if you've already installed any beta or RC installations for SP1, uninstall them first.
Hope this helps.
