rikizoo: the launcher show i m playing the game but only for few minuts than the game stop , the game doesn't start
And there is nothing related to Witcher 3 shown in Windows Task Manager?
If yes try this:
Q.: When I start the game nothing happens, but I can see the application running in the background.
A.: There has been a solution circling around that worked for quite a few people, thanks to Hycinthus:
1. Uninstall Galaxy
2. Open command line (Start->type "cmd" -> right click "cmd.exe" and click "run as administrator")
3. Type sc delete GalaxyClientService
sc delete GalaxyCommunication
4. Go to //gamedir\bin\x64 and rename or delete galaxy.dll
5. Launch the game, an error message will pop up, but the next time you start it everything should be fine

1. Are you using mods for Witcher 3?
2. Is there an error log in the Witcher 3 game folder?
3. Does the same happen if you start the game without Galaxy?
4. Were you able to play the game before you patched it?
5. Do you fulfill the mimimum system requierements?
Please answer as many questions as possible. More information = better help to find the problem.
