I have a co worker who uninstalled MS Office from their computer. She then attempts to install a different version of Office after rebooting and is given the error message that a 64 bit version cannot be installed on a 32 bit system. She is running Windows 7 64 bit. We have researched everything we have found on the net and have performed all of the lengthy procedures in an attempt to remove any and all remnants of the old Office installation, yet it is still not letting her install? I see all kinds of similar posts on the net referencing this problem, but we cannot get past it. Any suggestions?
