You will need a DirectX wrapper such as dgVoodoo 2 (http://dege.freeweb.hu/dgVoodoo2/dgVoodoo2.html) in order for ReShade to work. During installation of ReShade, choose client.exe and DirectX 10/11. If you encounter wrong colors, low framerate and other glitches upon startup, you will have to install the Microsoft Compatibility Administrator through this setup tool: https://docs.microsoft.com/en-us/windows-hardware/get-started/adk-install run it as administrator, go to "Applications", search for KISS Psycho Circus entry, right-click the entries there and choose "Disable Entry".
