I know this has been asked before, but I still run into this problem when trying to update an Office Xp Pro Corp install to Sp1....... The new Office update gives me no error message just goes through all the correct procedures, then tells me install unsuccessful. I know there is a way to slipstream sp1 into the cd install in the first place, if someone would tell me that, and even go into detail about doing the same with sp2, that would be nice. Thanks ahead of time.

Here's the officexp sp1+2 slipstreaming guide:
