So at my office one of the project managers recieved a new alum. iMac and we installed a new version of Office 08 on there after Migrating all his old files from his old iMac. Now his old iMac is being used by our new PM and when I go to install Office Mac 2008 it will not allow me to do a clean install (as in entering a new Product Key) just an Upgrade. And if I do just do the upgrade they cannot have Word open at the same time. How can I do a clean install?
