I'm on Linux. Installed the game using Lutris. The game runs fine but when I try to install the Natural Law DLC, it gives me the following error message:

"The base game was not detected.Please install the GOG version."

I installed the game to the default installation folder.

I ran the DLC exe both from the Downloads folder and from inside the game folder, neither worked.

I looked at the registry and the path is correct.


Any ideas on how to install the DLCs? I'd really like to play the game with the DLCs installed.

Hi,

I installed the gog version using the exe through Lutris. Everything went well and the game ran fine. But it gives me the error mentioned above when attempting to install the DLC.

I'm installing the game in a Windows VM now. If the DLCs install in the VM, I'll just copy the install folder to the Linux side and get my game on, hopefully :)

Thanks.

EDIT: I installed ISG and both DLCs in a Windows VM then, copied the installation folder over to where Lutris had installed the game on the Linux side and its working fine.

Only issue so far was ISG would crash when starting a new game but, after disabling DXVK/VKD3D in Lutris new games start without a hitch.
