Microsoft Office Professional Plus 2010 – Cannot verify the license for this product. You should repair the office program by using control panel.

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

Office 2010 activation - cmd

Office 2010 activation – cmd

This actually activates the product key with the office 2010 you got installed , and shows below messages as shown in the screen shot.
