Reshade not working with KOTOR

Hi, I can't get reshade to work with Kotor, everytime I run the game it just runs normal like if I didn't install anything, I'm using 3.0.6 version and OpenGL, (installed it selecting swkotor.exe), I checked the games compatibility page and says it's fully compatible, can somebody tell me how to install it? or maybe if I need an especific file to make it work?

Thanks
