License activation error, Win 10 broke computer, need to reinstall MS S&T on the same computer, now fixed. RRS feed

  • Question

  • Short story is windows 10 KILLED MY COMPUTER. It is now rolled back to Win 8.1, I am just trying to reinstall all the old programs back on. MS Streets & Trips 2013 says "Product key already in use" - I could not uninstall it first, as windows 10 just installed on its own (without my choice). So, need to allow one more activation to get it running again.  Chat associate was NOT able to help. Sent me to the forums only, and then it turned out it was the WRONG forum. Trying again here, hoping for an actual answer this time?
