Try redownloading 1.2, then uninstalling the 1.2 you installed, then reinstall 1.2 and make sure it installs in its own director.
I got it going again. Deleting and reinstalling ver. 1.2 did not work but after restoring computer to an earlier date before ver 1.2 then deleting ver 1.1 and reinstalling 1.2 that worked. Thank You
