If I start Movie Studio I get always the user account screen. The question is of this app may change my device.
If the button details is used, information about the Magix certificate is visible. The certificate is ok.
The answer Yes or No makes no difference, the applications works always after pressing Yes or No.
Note: I use Windows 11 home on a fast Acer laptop with i7, 16Gb, 500Gb SSD and GTX 1050 video.
Application is Movie Studio 18 Platinum, Version 18.1.0.24 (UPD3) UG code 5922 KA1
