if you are trying to install 4.33 you do not have to install the original falcon 4.0 on your main drive you just have to have the disc in your read-able drive.
I was going to install the previous version since 4.33 isn’t available atm. On my Falcon 4 disk the only .exe are the setup file and the autorun file.
EDIT Got it al to work. I hadn’t realized I only had to point the prg to the CD.
Thanks for the help.
