shishimaru1000: There's something wrong. Backup xinput (rename it), download x360ce for win64 and put it in \bin\x64. Open it, create the right files and close it.
anasschakik: can you please explain more clearly, I didn't understand
Sure. I don't know what went wrong with you, but let's try to begin from the start.
- Witcher 3 is 64 bit, so let's say that you'll need x360ce in 64 bit (at least, it worked with me). Search and download it.
- Put x360ce in the "x64" folder; it's under "\bin".
- There must be a file called xinput1_3.dll, just rename it (you can call it xinput1_3backup.dll)
- Execute x360ce, it'll ask you to create two files; accept to create them.
- Just use the program until your gamepad works.
- Save and exit.
Have you tried these steps correctly?
