This is not the case! If you insert the CD and allow it to auto-run, you will receive a message "The version of this file is not compatible with the version of Windows you're running...." yada yada yada. DISREGARD THIS MESSAGE! On the install CD there is a folder named DISK1. In that folder, run the Setup.exe and the app will install perfectly. Upon first run allow it to update itself. It works perfectly! https://www.gnu.org/licenses/lgpl-3.0.html
