If you are working on a Office 2010 deployment and no KMS server has been setup you may run out of the grace period. Office 2010 now requires product activation similar to Windows Vista/7.
The following Microsoft Office Activation Wizard may appear.
As I don’t want to activate the installation at this moment I will use the Office 2010 rearm feature available.
- Start a elevated command prompt (cmd.exe).
- Go to C:\Program Files\Common Files\microsoft shared\OfficeSoftwareProtectionPlatform
- Run OSPPREARM.EXE
After the OSPPREARM.EXE has run you will get the “Microsoft Office rearm successful” message.
