I have a genuine version of Microsoft Office on my Macbook Pro, but I gave it to everybody I know, not knowing I could only copy one. So now my version is being used by at least 10 different people I dont even see anymore. How can I delete their versions without using their computers?? I keep getting messages that I cannot use Word because it is already in use by somebody else (or sometimes I even get specific names). I dont want to reinstall my own version because I dont have the productkey anymore, I just want all the other people being stopped using my version. Is there a way to do this? Or can I change my license so that no one can use it anymore except me? I just dont want my name showing up at random computers which happen to have my copy. Thanks in advance!
