DLL for class not found:

Spoiler

This error can occur when you run the game from inside a OneDrive folder like Downloads/Documents or even from the Desktop, move your game folder to your disk, C:/ or D:/, and it should work.

Missing DLL files

Spoiler

This error occurs because of missing visual c++ dll files, you can get them by following this quick installation from Microsoft: https://aka.ms/vs/17/release/vc_redist.x86.exe

Unspecified error on Mac (using parallels)

Spoiler

The solution to this is to change the game's resolution (using the config.ini file from the game folder) to the Mac aspect ratio of 16:10, for example from 1280x720 (default) to 1280x800
