I recently installed Witcher 3 manually by downloading the .bins and running the patch and and I can start it up (Via the executable). I want Galaxy to be hooked up with my Witcher so it does auto updates but when I try to import my folder to my already installed witcher folder it says "Disk access problem". Please help

solution is here:

1. Quit GOG Galaxy
2. Open your "the witcher 3" installation folder
3. Delete goggame-galaxyFileList.cfg and goggame-1207664643.info
4. Lauch GOG Galaxy
5. Go to your library : The Witcher 3.
6. Click on "MORE"
7. Click on "MANAGE".
8. Click on "VERIFY/REPAIR" If greyed out Import folder and select where your game is installed
9. Let the launcher check the file and download something.
10. It should be ok.

disk access? is gog galaxy run as admin?

if so try to run chkdsk on your drives to make sure they're not corrupt.
