Sorry on advance if this is the wrong area. I purchased Microsoft Office 2010 Professional for Windows though the Home Use Program about a year go and now converted both my computers to Mac for obvious reasons. The HUP only allows one purchase. Can I just use my Windows product key with Microsoft Office 2011 for Mac? I already have the installer from my wife's HUP purchase of Office 2011 for Mac. I just need a key to use on the 2nd Mac. I won't be using the Windows version anymore and have no need for it but, don't want to waste the license either. So, I figured this should be allowed. Other options are: 1. Can I use one key on 2 Macs? 2. If I call Microsoft will they exchange keys for me since I have a legit copy and aren't trying to "steal" it? What do y'all think?
