When buying this year’s update version of Magix Video Deluxe Plus (International name is Magix Movie Edit Plus) in it’s 2018 version, it’s shipped with a free copy of Music Maker Movie Score Edition (which is a variant of Magix Music Maker 2015)
I found an issue with the Music Maker always finding a new update, when I downloaded it over the update assistant, the update setup told me that it requires Magic Music Maker 2015 to be installed. So you are in a devil’s circle!
So, here is the solution:
1) Download the last official update: 21.0.4.50 (German version / English international version)
2) The setup routine of the update will say that the latest version is already installed. Select “repair installation”, this will install the update
3) Check for new updates in Music Maker again and it will tell you that there are no new updates available.
