This is a good one,
For some reason loads of people are having trouble installing Office 2007 SP1 an update windows considers not optional, nor recommended, but important. Until now I was one of those people. There are loads of forum posts knocking about that recommend reinstalling, repairing the installation and most agree that you need to do these things with the office cd in the drive else you’re screwed. They’d be wrong.
Apparently, you do need a disc in the drive but it doesn’t matter what it is! I actually had ‘Gattaca’ in the drive (a damn good movie).
After a couple of failed attempts I couldn’t believe how simple and bizzare the solution turned out to be. I found the solution here and now I find the fact that it installed without a hitch because I had a DVD in my drive hilarious. There were some forum posts where people claimed to have attempted to install the service pack up to nine times. I think they need to learn how to use search engines better.
