Reshade 3.0 - how to uninstall it ?

Hi,
I was using Reshade 2.0 for Flightsimulation Prepar3D v3.4 (i7-4790k, GTX980Ti) and it was working fine. I installed 3.0 today, but it does not work at all. Shift+F2 opens the Reshade 3.0 window, as expected, but when clicking “continue” or Settings or whatever, nothing happens at all. The only thing I can do, is to close the window again. My monitor resolution is 4096x2160
Please let me know, which files I need to delete, that I can reinstall 2.0 again.
Thank you
Bruno

dxgi.dll

Thank you for your quick reply.
Question; is there any chance to get 3.0 working in P3D ? Are there any improvements in 3.0 over 2.0 ?

Certainly. 2.0 has no in-game GUI for starters. But I don't know if I can find and fix the problem you face that easily, since things seem to be working great in all other games that were tested so far. If something similar occurs in a game I can get access to, then I'd likely get it fixed, but otherwise I can't guarantee anything.

Thank you for your great support.

What about for IL-2 which is a DX9 game as I haven't got dxgi.dll

Ill be reverting to 2.0 s 3.0 crashes my game. Thanks for the awesome software!
