Screensavers should work just fine on Windows 10. Could you please send us the screensaver file and the project files to http://www.blumentals.net/scrfactory/su ... ontact.php ? Also please send the screenshot of the error message that you get.
The only exception is logon screensavers - they don't work on any Windows versions, Screensaver Factory does not support logon screensavers.
