Hi, I installed Messiah a few weeks ago, but I got hooked in another bl so I uninstalled it to save space. I'm finished with the other game so I wanted to return to Messiah but now I can't install it: when I mount disc 1 on Daemon Tools, and I open the exe file, this appears.

I don't know what's the proble, does anyone know?
Thank you in advance.
