I've sent an email to the vendor, but am posting here to see if anyone else has had this problem.
Absolutely clean Windows 10 x64 install. Only other software installed is Rhino 5, the MadCam 5 plugin, and the Google Drive Client.
Downloaded "setup_1.1026.exe" from cncdrive.com.
Launch installer and get Windows "Do you want program from unknown publisher to make changes..."
Click "yes"
Installer just quits
I've downloaded several times, I've rebooted. It don't get any screens or errors. It just quits the installer after I click "yes" to the Windows Account screen thing.
Has anyone else had this problem? Can anyone think of a solution? Obviously I'm peeved because I already paid for a license from cnc4pc.
