I got a problem faced in one of our dev machines which is eventually a VM while activating the product key. We had this problem almost for about 12hrs but couldn’t be to resolve even after multiple re-installs and restarts.
What I have did is below:
Went to Control Panel – Selected the Office program and Repair Office
Entered the product key
Reinstalled the office products
Rebooted the machine
None of the above worked.
Finally I pinged one of my friend who is an Office MVP and he given me some inputs
Go to command prompt and enter the command
Cd C:\Program Files\Microsoft Office\Office14 (Note if you are running 64 bit then go to C:\Program Files (x86) \Microsoft Office\Office14 ).
then type below command
cscript ospp.vbs /act
This actually activates the product key with the office 2010 you got installed , and shows below messages as shown in the screen shot.
