Hi Igni. Don't worry about replacing the .exe of files. Just set them to always "Run as admin" and what I did is just Installed the dxwebsetup.exe then used the reshade with the 0.18.0 .dll and it works fine.
Search it here --> sfx.thelazy.net/games/preset/4963/ Should you have any concern about it just message me. Wasn't able to go online since I'm enjoying Tera reshade for months now.; xD
