Bought 2022 version of Magix Movie Edit Pro via upgrade from older version. Downloaded the install file. Double click the install file. Get the Windows 10 prompt to confirm changes to system. Install progress window shows very briefly. And then nothing!!
Try deactivating any antivirus software you are running and Windows Defender for the duration of the downloads.
Because the installer and program download relies on two way communication while downloading it is sometimes mistaken as virus activity and is blocked.
