I sent you a DM before I saw the post here. I uninstalled, restarted my pc and tried to reinstall with the files you suggested. I made sure to follow the guide again, but I'm still getting that same error. Any other ideas?
Let me start with I feel like an idiot. I found an english copy of DO on an abandonware site that linked to here for install instructions. I've followed the steps in the ultimate guide, and I've watched the youtube video. I followed the video step by step and paused often to make sure I was doing it right. After step 4 the game won't open. It starts to, I get the black screen right before the logo video starts, then I get the error Dark Omen has failed due to an incompatible DirectX version or out of date display drivers. I've checked the compatibility options for the EngRel.exe folder. I've used the regedit files for win 10 64 bit that came with the patch file you linked in the install guide. I'm not sure what else to do. Any help would be greatly appreciated.
