From time to time Microsoft Office licensing gets confused and you end up having activation problems, say, in a situation when you install Office Small Business and then decide you want to give a try to Office Pro. When you remove it or uninstall the Pro version – Office can get confused and even though you do not have the Pro version installed any more it asks for activation. As a result having your legal/valid copy of Office Small Business unusable. This is because “higher” version of Office takes precedence over the “lower” ones. This is somehow logical – just removing sometimes fails. Well, it just happens.

It turns out, that Microsoft itself is providing a tool that can be used to clear that mess in quite easy way:

  1. First, we need to check the licenses we have:
  2. Open up elevated command prompt and find out what licenses you have:
  3. now, find the one that should be removed or is giving problems, note the last 5 characters of license key and enter below command:
  4. Press Enter

If everything goes well, license should be removed and your Small Business license should be up and running or require Internet activation – but this time it should work without problems.

Hope this helps!
