Since the method in the thread [ 35862-Microsoft-Office-2013-Preview ] (which uses MultiKMS and a retail MAK) worked well for me (eventhough it uses online activation after all), I was wondering on how to backup the activation tokens and license. The [Microsoft Toolkit 2.3.2] tool tells me there are license issues / that they are broken - eventhough I have 2010 (32bit) and 2013 (32bit) activated and working well on the same Windows 7 x64 machine. I always get "Cannot use Backup because your licensing details are corrupt." :-( Any ideas? Thanks!
