I'm having the exact same problem as this topic:
However I need further assistance because I just bought Vista Ultimate (retail) and did a fresh clean install with a format to C: even. A fresh install was the accepted solution but in my case it appears there is more to it. I installed Vista about 4 days ago and after installing Office 2007 Professional (with EVERYTHING selected to run from the hard disk) I can't seem to launch ANY office application without the "Please wait while Windows configures Microsoft Office Professional 2007" and then 2 minutes of configuring taking place each and every time I launch an office app. There are many solutions and KB articles for other versions of Office and Windows but I need a solution for Vista and 2007.
Please help! Thanks!
