@Nevaehy Thanks for sending me the bin folder. I have extracted it, and both in the "x64" and "x64_dx12" folders, once I double-click witcher3.exe, it greets me with this dialog: I don't know what the difference is between our systems then. Which exact Windows version do you use? (Open "About your PC" and then press "Copy" in the section "Windows specifications".) What antivirus do you have? Can you try launching it with your antivirus disabled? Antivirus programs may have very nasty and deep integrations with the OS and the way applications are launched. Also, disable any other programs that modify program behavior, such as programs that add overlays (Steam/Galaxy overlay, FPS counters, programs that add additional shaders etc.). Let me know if that helps, and if so which specific step helped. For people where the mod does not work on Witcher 3 v4.0.0, did/does it work for you on v1.32 (and if so, was it the v0.1 or v1.0-rc1 version of my mod)? Also if there is anyone for whom the v1.0-rc1 version of my mod works, let me know (I have only gotten responses from people where it doesn't work so far).
