Removing License Files for Microsoft Office 2011 for Mac:

  1. In the Finder, click Go, and then click Computer.
  2. Open your hard drive. For example, Macintosh HD.
  3. Open the Library folder.
  4. Open Preferences folder.
  5. Select the file com.microsoft.office.licensing.plist and move it to Trash.

These instructions were taken from Microsoft's website so I don’t know if there is any easier way to accomplish the same task. The website also has more detailed information if you’re look to completely remove Microsoft Office 2011 for Mac from your system.

If someone knows an easier way, I'm sure they will post it.

Thank you so much. This'll do nicely. :)
 
Sending the plist file to trash sounds questionable as I tried doing an install yesterday and it told me that I had used the key too many times. Simply deleting a file isn't going to let MS know that the key should be available for use again. Also, I thought I read something in the license that said you could do a one time transfer to a different device and that was it. The whole thing was rather confusing to tell the truth. There were several options for what type of license you have, which might also be different for you. I'm not saying I know the answers here, but you might want to do a little more checking. Also, if there is a way to deactivate, I would think it would be from within the App.

I had this same problem when I switched computers. I used Migration Assistant and couldn't get Office to register on the new one.

In the end I used CleanMyMac2 to remove everything associated with the Office install on the new computer and started fresh. That's how I got it to work.
 
Back in my Windows days, when faced with this, the install/activation screen gave me a link where I could "challenge" the assertion and enter a series of codes. Once done, I believe it asked how many computers the software was installed on, and, eventually, it allowed me to activate the software. Kind of a pain, but from M$'s perspective, I guess it's understandable.

I have not faced this situation since switching to Mac/OS X in 2010, so I cannot say if this has any relevance to your situation or not.
