I have the above mentioned program installed in my PC. I am using xp pro sp2.When trying to start the program from the desktop shortcut a window appeared stating; The folder path " Program files" contains an invalid character. I have tried to reinstall the DVD again and the same window appears, I have tried to remove the program from the add/remove and still the same window appears. I have even been to the search all files and folders and nothing remotely similar to (encarta 2005 premium suite DVD" comes out. I have deleted all d/top shortcuts in an effort to remove any traces from this program so as to try a clean reinstall but to no avail.Any advice greatly appreciated, thanks.
