I've tried both versions and even file sharing but no matter what the game will always try to open autocad, even though on the other computer it works flawlessly.
I have however found a workaround. As it turns out, the autocad installer seems to prevent one window from loading correctly, and that window will be the first one I open (i. e if I open Economics as soon as I start the game, economics will not load properly until autocad installer gives up after a few hours. Right now I'm just loading in the sector info since it's the page I use the least, and then load up system map and everything else works fine.
This is pretty annoying since every time I want to do anything with sectors I have to save and restart the game, then save and restart again but at least I can play now
