All the extra pack content were installed but the software keep asking me on startup if I want to install and if I click yes it launches the installer that does not let me tick any box
This would suggest your Antivirus Folder protection/Ransomeware feature is blocking MEP from updating a file it uses for startup - try turning it off and then repeat the procedure, activate the dialogs and restart MEP, when the popup appears click the Do not show this message again option first and then click the Later button.
I resintalled windows and Magix Pro X ... same issue! I attach a screenshot you can that even though they are installed Magix pro X is still asking me what to do with those every single time I launch the software ...
Big bug ...
Is there stil la way to contact directly Magix support ? Everything I try is just poiting me here to the forums ...
Just a thought: did you download and install ALL the additional content? Your screenshot shows a section of the download screen. If you scroll down is there something lower down that is still showing as available?
Yes I installed everything on the first launch and I can see all the elements installed but I still have the notification every time I start the software ...
