[SOLVED]

The game requires the python310.dll library, and Python 3.10 requires a minimum of Windows 8.1.

Please update the minimum requirements in the shop, as this game, although retro looking, requires a very up-to-date operating system and will certainly not run on every PC!

What can I say...

When trying to launch the Warsim game, an error message appears:
"Error loading Python DLL..."..
(see attachment #1)

Attempting to install the DLL libraries, ends with another error message:
"Setup failed (...) At least Windows 8.1 or Windows Server 2012 are required to install Python 3.10.10 (64-bit)."
(see attachment #2)

I am happy to report that the issue has been resolved by GOG support :)

The problem turned out to be apparently not the game itself but the launcher, and it was the launcher that was reporting missing Python libraries.

The game launched directly via the 'Warsim.exe' executable file works perfectly.

Thanks!
