Was unaware I was supposed to do that and I have no idea where to find that specific .exe file you are referring to, it is not in the dune 2000 folder that the game and everything that came with it is in. I tried searching for it specifically but all I got was the files that I downloaded and couldn't open. I don't know if it is a coincidence or not but the last few times that the game has froze I noticed that specific actions were being performed(ei something finished building or most recent me trying to open the pause menu). Idk what is causing it but I am nearly done with the last campaign and if a fix can't be found by then I'm just gonna say my computer doesn't like old games with no disc and leave it at that.
