. . . . What are the steps to migrate my MEPro (2021) software to a new computer? . . . .
Backup all your projects, source files and any other related files you may have created, preferably to an external hard drive if you have one. Note the folders used for your project related files on the old computer
If you have installed on 2 computers already, eg PC and laptop, then uninstall MEP 2021 from the old computer - this should free up the activation slot in your account
otherwise
Install MEP 2021 on the new computer, activate and download/install all the extra content.
Copy the backed up folders and content for the projects to the new computer maintaining the same folder structure - this will avoid having to search for the files used in the projects.
Adjust the program Folders settings if necessary and check everything is working.
Go to the magix main website and log into your old account using the email address and password you used to set it up. From there you can download your product and password and if needed, de-register the program on your old computer.
