i don't understand anything regarding the install of the engine at all. is there a step by step by any chance? or something else to follow other than the pdf provided? thanks!
The quick answer is find the path to the Maelstrom.exe you want to run on your machine (where did you put it?). Find the ERAS path for the Program/RESOURCE folder (where did you put it?). Then modify a Windows Shortcut with the Target = the path to the Maelstrom.exe you want, and the Start in = the path to ERAS stuff.
Use the shortcut to launch the game.
