Hello Chaps,
I've decided to install WWII Fighters on my PC, after a two year break from this sim, but alas, one has come across a rather annoying problem!
When I try to install, I have a box pop up with this message;

Has anyone else encountered this problem, and if so, how was it rectified? All suggestions (polite ones please lol) would be very much appreciated!
Regards,
Pathfinder
