I've tried every single fix I came across, but to no avail. Trying to launch in every compatibility mode (+ as Administrator), turning off frame buffer effects and shadows, turning off videos, removing the biologo.bik, leclogo.bik and legal.bik files, turning off thread optimization in the NVIDIA Control Panel, launching in windowed mode, turning on and off vsync; tried every one of them, but none of them worked.
Not to lie though, launching in Windows 98 compatibility mode did work, but when I try to start a game in this mode, my screen just turns black and immediately crashes (after character creation), after which I'm forced to reboot my computer, because it won't allow me to shut down the game via Task Manager.
I'm using a Windows 10 laptop with an NVIDIA GTX 960M graphics card. I would say my system is not the problem, because like I said, the games ran perfectly when I had just bought them, and that was on the same system, so it's really strange they don't launch at all now. Nothing changed in the meantime, except for a regular Windows update last week that I can think of, but I have no idea what this could have changed on my system.
After KotOR gave me trouble, I checked if my other games were still working, the old and the newer ones, and they all ran fine.
So I'm asking you if I'm not missing something really crucial here, and if there is any possibility to run these games ever again on my system. I fear the worst though, because every thread I came across on the internet with the same problem I am having now, didn't give me any solution either. :(
