Thanks for reply. I was able to reinstall Office2003 but only after I uninstalled it. I think it has something to do with the file proplus.msi. Somehow I think CCleaner changes or removes it as it wants me to first insert Office2003 CD but it won't accept it when I do. Very weird as I don't see any category in cleanup that removes *.msi files. Others don't have the problem but I ran CCleaner on a frinds MSI board and the same thing happened.
Any thoughts?
