At the start up of my programme, I am notified that Magix Video deluxe 17 Plus is not compatible with windows Aero and the color scheme has been changed to windows 7 basic. Why is that so?
Right click the shortcut/icon for MEP and select Properties, on the tab shown check that you are not running in compatibility mode as shown in the image. If the check box is as shown - uncheck it and click OK. Then run MEP again.
