I am trying to completely remove all traces of Office 2013 so that I can reinstall office 2010. I have spent hours researching the issue and trying different things but every time I install 2010 (pre cracked, tested and works on another computer) a box pops up telling me about some configuration process. This takes several minutes but always tells me to reboot the computer, then afterwards the same box pops and and we go through the loop again and again. Canceling the "setup process" (the box that pops up when I start any office program) just terminates the program. Does anyone know how to remove ALL traces of office and the previous license keys installed so that I can install 2010? I don't want to reinstall windows again, too much hassle.
