I recently had to do a clean re installation of Windows 10 Pro 64 bit. I lost the up to date details to re-install Designer Pro X (17) I downloaded the latest version (new 18) Please how do I re register and activate it ?
Go to your Magix account, log in, go to My Products and you will find the details of your XDP 17 installation (serial number and installer).
BUT. that serial number/activation key will almost certainly NOT work for your installation of XDP 18! So, you will have to completely uninstall XDP 18 - the usual suggestion is to use the free Revo Uninstaller to successfully do this, just make sure you carefully follow its instructions - before then reinstalling 17, unless you are willing to pay for the upgrade to version 18. You will then receive a new activation key.
