Have you tried a compatibility mode on the 'setup.exe' file?
Thanks for the response Flyboy, I've tried every compat' mode, copy to desktop and,
other stuff that i could think of. I think the installer doesn't like the 64bit
environment.
I even tried copying the folder over from my XP-Pro computer: that greyed out the missions tab. Anyway, i'll keep trying and post back a result when/if i get it done.

P.S. I will eventually try WIN-XP Virtual mode as i have that installed.
