I tried a bunch of things that I found on the steam community (And yes, I do have the game on steam) from users having the same issue, but none of them have worked.
As I wrote on the Steam Community Forums "I've tried setting the files to not read only, "Taking Ownership" of the files, writing in my own save file in the documents/my games/fallout4 file, and reinstalling the game. I'm at my wits end."
The only thing I can think is that sometimes when I set a file to not be read only and hit apply, I go back into the properties and the read only box is checked again. And yes, my computer account is an administrator account.
I'm also having a problem regarding how the game launches only in windowed mode, even when windowed mode isn't checked.
Please help me as soon as you can, I'd really like to play the game! Thank you in advance!
