I'm newly registered so I hope my posting is to the correct Forum and I did search first in case my question has already been asked but couldn't find anything: I purchased and installed Office for Mac Home Edition and now have the opportunity to buy the full licence for the Enterprise Edition. Should I uninstall the home edition first and then install the enterprise version? If so, will this affect any files (excel, word, powerpoint) I have already saved? How do I uninstall Office 2011 Home Edition - I'm new to Macs! Many thanks in advance for any advice.
