Hi, I am about to install after Office for Mac 2011 (1 Licence user), on my imac. What happens if I have to send my imac in for repairs (hopefully this will never be the case), and i receive a new one. Or I buy another Mac. In the first szenario as my licence has been used on the broken will i have to buy a new copy of office. And in the second instance am i able to de register the software by a simple deinstall and load the software on my new Mac?
