I just finished updating to #7 of this series and it hangs again (says: Installing Page at the very top). After about a minute I decided to quit Malwarebytes and it immediately finished installing something that is part of the mod but I didn't catch exactly what it was; and then it completed normally. So it may be a new file that MB screens very slowly. I will run it again without MB running and report back momentarily.
Success! It appears to be a Malwarebytes issue, for me anyway. The file was the minimaps_HD thingy if I read it correctly. So I quit MB and the install performed perfectly. Welp, time to go bust some armor. Hope this helps someone.
