I just ran a clean install of windows 7 this morning, installed all the latest updates, and I'm now trying to install Office Ultimate 2007 that I purchased last year from the Office Ultimate Steal. It was running fine under windows xp, but when I try to run the installer in windows 7, I get an error message that says: The installation of this package failed I have tried the following: Running the installer as administrator Running the installer under windows xp (SP3) compatability Mode Re downloading the installer (I have it saved to my dropbox account, I can't redownload it from Microsoft) Any help that you can provide would be great!
