Thank you for the help, it did help. In case anyone else has this issue, just delete the entire swtor from your PC and download the installation file from swtor.com and install it this way, it solves the blue screen problem.

Unfortunately, despite your efforts to help, nothin solves this. Can this even be solved? At least by me, the user?

Yep, still nothing. Disabled the RTP, and the launcher seemingly opens, as in it shows up in task manager processes, but the launcher does not open on the desktop...

So, yesterday I once again subscribed to SWTOR and already played for some 3 hrs, today, I turn on my PC, as usual, then I try to open the launcher, nothing happens, then blue screen, and it shows this - driver_irql_not_less_or_equal. Funny thing is, yesterday there were no issues, and I have changed absolutely nothing, updated nothing. My PC is exactly the same as it was yesterday, but now TOR just does not work. What should I do? One more thing, I played with a friend, who also installed the game, subscribed, etc. And he TODAY has the same problem. Same blue screen with the same driver_whatever.
