[Solved] "Flash Plugin not installed" in small preview on Windows 10

edited September 2018 in Flash (SWF)
My Flash-based screensavers created with iScreensaver Designer 5 work just fine on Windows 10, but in the Screen Saver Settings panel there's always an error message stating "Flash Plugin not installed, unable to display X.swf. Please install the Flash Player Plugin". See:

Can anything be done about this?
