Due to continuous Access errors, I decided to reinstall Office Professional 2010 (64 bit).

As I couldn’t find the original CD key I installed it with, I used another one from another installation. So far so good, installation went fine, etc.

Once I started any Office app, it popped up this error: “Microsoft Office professional plus 2010 cannot verify the license. blablabla useless crap check control panel”

I’ve tried:

  • Reenter CD key (via setup)
  • Repair Office
  • Install every single item I could select during the install
  • Remove office + reinstall office
  • Removed CD key with this
  • Reboot over a zillion times
  • Cursed
None of this worked.

However, this seems to fix it for me:

  1. Open command
  2. cd C:\Program Files\Microsoft Office\Office14
  3. cscript ospp.vbs /act
  4. reopen any Office. No more errors. Yay
