Problem installing Campaign Jena-Auerstaedt

[Mesquite]

Yeah, I install all of HPS games to the c:\Hps folder. I've had no trouble installing any other HPS games. the computer just hiccupped on this install and I interrupted it. I think now when I try to install it there's something on the computer telling the install program the game is already installed although it isn't. I've contacted HPS support and still waiting for a reply.
