Hi,
DaveWfg, and welcome to the forums.
First off, a bit of information. Microsoft Office (in any way, shape or form) does not come installed with *vista* - rather, it came installed with your machine because your manufacturer put it there.
Now, on to why it seems to be not gone - it could just as easily be a *third party* program that interfaces with Microsoft Office that is causing the problem - can you either post a screen shot of the error message you are receiving, or else tell us *exactly* what it says?
