HI guys!
I-m trying to launch CC IV Battle of the Bulge and I'm receiving an internal error message 0x473FA9. Does anyone have any idea on how to work around it?
Thanks

I would be surprised if there is a solution for Close Combat 4 internal error 0x473FA9.

But try setting the compatibility mode to Windows XP (if it's possible for your OS) and Run the executable as Administrator.

Try to ask for solution here:
