As @PATIENT-X has said, these are public, user to user forums and confidential data should never be posted here.
Instead you need to do the following:
To download the installer for your product to the new computer, from that computer go to your Magix account, log in, go to My products where you will find a link to download the installer and to see your product key, which you will need in order to activate the new installation.
At the same time whilst in your account you should deactivate the installation listing for your old computer, assuming you no longer need it.
