Version 1.2? That's strange as 3.1 is the most current and only version that you can download from the site. (At least last as far as I know) Also, only 3.0 and onward have the in-game interface.
It's also possible that the 3.1 installer used the wrong binary file, which would be quite odd.
After some examination I noticed that I was hovering over the old 3.0 version in that screenshot. Regardless neither versions work after a clean install. No mods or anything have been added to my game.
The version that I downloaded from the website is called: ReShade_Setup_3.1.0.
But when I go to the file description It says version 1.4. Could you possibly upload the latest reshade install file, or the one that worked for you.
