I addressed this issue to GOG support, this is their reply:
Unfortunately we are unable to release Linux versions of our games, so the installer will only work on a Windows system. If you wish to try playing a GOG.com release on Linux, the best workaround (aside from setting up a dual-boot Windows XP system) would be to install and run it through some virtual machine software, though I can't guarantee that these will work. You could check our forums for instructions on running many of our games on non-Windows platforms as well, since manyof our customers are Mac/Linux users.
> Hi. I bought this game. But I found that Mac and Linux version are not provided. Could you provide them so that I can play...?
> Thanks.
So I guess there will not be Linux/Mac version in the near future.
