Within the last few days, I've begun having a problem with fceux, where as soon as I double-click on the fceux.exe to start the emulator, the fceux window opens, then it immediately closes. It didn't previously do this at all; it was working just fine, no problems at all. I don't recall having changed anything that might mess with it, and even the latest clean git build was having the same problem. Other emulators I have in the same parent directory all work fine, including jnes, which points to NES ROMs from the same directory that fceux points to. So I'm guessing it's not my ROM collection that's the problem here either. Am I missing something here that might shed light on this problem?

Strange. I happened to run the Windows DISM and now fceux starts up just fine. I have no idea what might have caused the problem, but it seems to have gone away. I'll close this issue.
