So I encountered this:
"People are getting faulty installations of the game where even if it installs and you can run it, if you close it and try running it again i won't launch.
Worse, if you try deleting and reinstalling, it will only delete the launcher which is about 11GB and will leave about 50GB behind in a hidden, untouchable folder. If you ignore it and try reinstalling it will not write over this data but instead duplicate it, so your hard drive will soon be out of 100GB of space.
You have to do some major fucking around in order to brute force your admin privileges in order to delete it."
Not too terrible to allow permissions but yeah, fucking stupid.
