I was able to apply the SP-1 update to the Corp. Office Xp Professional. The problem now is the adminstrative installation files are just under 1gb. I looking for a method or a program that will compress that 1 gb to fit on a 700mc cd-r which will retain its functionability as installation files without having to go through the process of unzipping files to do so? Is there a way to take a file (non dvd or mpeg) and compress it through divx? Any help appreciated.
