i had developed project in Movicon next version 4.3 build 373. It was working fine in the pc i developed. and also worked on others pc we ported on to. However, i have not installed movicon (same version) in my new laptop (win11 prof, 64 bit). the project server runs properly from the Movicon environment. But when i execute the runtime , my screens are not opening. (i tried both Tiles page and Main screen option from the project property), it gives me same kind of errors. The runtime just hangs. I have to Ctrl+Alt+Del and end the Runtime task from the taskend. Method not found: 'System.StringScreenSettings.ScreenDocument .GetServerAppNameProperty(System.Windows.UIElement) However if i run the demo examples of movicon, they are running fine. Please help urgently to resolve the issue thanks in advance , Vikram
