Discouraged in CNEWS and here on finding a solution on running Ventura 10 on Vista 64 Bit , I sought a way to install the program anyway.
Create a directory on the desktop, copy the entire Ventura CD into the folder. Select the Setup32.exe file and right click and choose properties. Set compatibility to XP. Check Run as Administrator.
Double Click the file and Ventura installs.
It launches and appears to run but I shall do some more testing.
