While I cannot answer for every computer/opsys/version etc., this is how it works with my particular situation (US-EN, Win10 Pro):

1. Use the MAGIX downloader file (it will have "dlm" in the file name). Download it and run it (with admin privileges). This will be provided when you request a particular download in the support area once you log in to your MAGIX account.

2. When you run this downloader file, your full EXE installer files will then be saved to your computer during its install process. In my case they are saved to the following folder path: <youruserdocumentspath>\MAGIX Downloads\Installationsmanager

3. Look there for the full EXE installer files once you have completed everything.

This is how it works for me... but if this isn't the case for you I cannot assist further. BTW If you DL additional addins for your MAGIX apps, the installers for those may be found in the parent folder

<youruserdocumentspath>\MAGIX Downloads\

This all assumes that you have a valid login account with MAGIX, and that you have registered your purchased MAGIX apps with them! If MAGIX doesn't know that you own one of their applications, then you can't get to them.

I hope this helps you and others! Be safe and well!
