Same problem as everyone else, ntdll.dll is the "faulty module" for me (when using XP SP2 comp. mode).

Long time has passed and I still get this error.

Out of curiosity, has anyone managed to get GC1 (or 2, if it has issues, too) working on Win10 with FCU and v1803? This looks like a really interesting game (just wish you could choose your faction, so you could experience both sides of the story), but I laid over US$1700 on my current machine about six months ago, and it'll take about a year of saving up to afford another machine with a more optimal OS (like good ol' Win7).

Off-topic, but you can always Google how to create a second partition and dual boot Windows 7

I didn't even know this was possible. Thanks a million! Definitely going to look into it!
