This program can be run with Windows 7, you have to install Windows 3.1, which will run GEN4. The process is not all that easy, but I have done it and it works. Google the various terms to find the web sites, which describe how to do it..
You first download and install DOSBox. Then find installation disks for Windows 3.1 or a web site where you can download it. Install Windows 3.1 in DOSBox. Run GEN4. The display is useable, but can be improved by changing from the default. The instructions are provided on the web site. I have not found out how to install a printer. You will have to get familiar (or re-acquainted) with DOS and Windows 3.1 commands.
I have no idea if this procedure will work with Windows 8 or 10.
