Try turning off any antivirus program you may have and disable Windows defender while the process is in action and completes.
Sometimes these programs can give a false positive as the program tries to verify the code is correct with the Magix servers and blocks the communication.
If that works then I would suggest adding the Magix folders to the 'exemption from scanning' section of any such programs as the program will from time to time try to reach the servers to scan for updates to the store content or other activity.
