I am trying to install Autodesk Civil3D 2008 on my new Windows 7 (64bit) machine and it says its unable to install due to the program being 32 bit. I read something about running in 32 bit compatibility mode to run the 32 bit program but am hesitant to change my settings and am a little unfamiliar with executing my machine into 32 bit compatibility mode. Any suggestions for enabling my machine to install/run this program, and any 32-bit program for that matter in case I run into this problem again.
