Unable to install GTAIII on Debian 10! Gives “product not supported on this os” after accepting licence agreement, see below screenshot and logs
Probably that message is referring to the windows version configured in Wine (i.e. WinXP, Win10,…).
Try to modify that parameter and then try again to install.
solved - attempted install. after it failed, changed wine configuration switching to windows XP, pointed the lutris executable to the setup.exe on disc, hit play. After successfully installing, switched executable back to gta3.exe in the install folder, hit play, game runs!
