Hello everyone,
I have download all .bin files (from GOG.com) and run setup_witcher3_en_goty_2.0.0.51.exe on my PC (Windows 7 64).
The files are and the game are now installed on my internal second drive (not on the system drive), I can launch the game but the keyboard is inactive. In the game option I see both controller and keyboard keybinding but when I try to change shortcut (or keymap) e.g. spacebar , nothing happened.

Could you give me some infos on that strange behaviour ?
Is that could be because the game is turn in english and my keyboard in AZERTY ?

Thank's for usefull help, I am still stocking on this bug for 3 days !

Try verify and repair game.If that is okay I would reinstall.If that fails then windows OS could be the problem.Or you could just contact support and see if they have a solution.

Thank's for your answer.
I try everything that I could, recently I give enough free space disk on main drive for reinstall the game on it but problems persist.
I contact support and wait for answer...

Yes,that could be best idea for the problem.
