This may or may not help. But I’ll give you the basic steps using wine only and no Proton magic to run a game from disk:
- Create an empty folder to be your wineprefix (emulated system folder) or use the default.
- run
WINEPREFIX=[full path to new folder] winecfgcommand in terminal (justwinecfgif you will use the default prefix). - mount your CD so that you can see it in your file browser. (Might be simply clicking that device in the file browser when a CD is in the drive bay)
- In the winecfg set drive D: to point to the folder where you mounted the CD.
- run the CD installer with wine… e.g
WINEPREFIX=/some/path wine /media/something/cdrom1/setup.exe, install the game to C: - run the game with WINE on the same prefix and with the CD inserted and mounted (if there are resources on the CD or basic DRM) e.g.
WINEPREFIX=/some/path wine '/some/path/drive_c/Program Files (x86)/Cool Game/coolgame.exe - if that works, you might be able to create an image of the disc and mount that instead of the physical CD, you’d then rerun winecfg and set D: to the correct folder where the disk image is mounted.

Xitter comments indicate that the PCs should be of sufficient spec to achieve a good sell value. So if it’s not Win 11 compatible then Sofmap can’t price it in hopes to resell them according to the social media responder.
