Hey guys. I recently downloaded and installed Office for mac 2011. Unfortunately, i had already had a different version of office for mac that contained a different name (my friend's) who had licensed the product and registered for it. Now that i paid and have office for mac 2011, i'd like the product to be installed, licensed and registered under my name. unfortunately, i don't know how to change the name that says it's still registered to, when it should be registered to me now. any help? thanks.
