Restoring a License

Licensing Process

Registration Codes are permanent licenses. This is the code that you received via email when you purchased Media Center. If you lost yours, they can be retrieved by using option #2 on the Restore Page. You will receive mail from buy-button at jriver.

Version is important. Your license must match the installed version of MC and platform. Windows, Linux, and Mac licenses are separate, as are major versions from one another (MC18 versus MC19). Older versions are on our wiki if you need to obtain an installer for a previously purchased older version.

Download and install from the Download Page at jriver.com or from our Interact Forum. Other sites may not be trustworthy.

Restore a license by using the Registration Code on the Restore Page. In MC18 and above, this can be done from within the program, under Help > Install License, or within the startup dialog shown by the trial. You must have the correct version of MC installed first.

The Install Key is a portable file (.mjr file type), generated when you restore, and which will be automatically applied. It will also be emailed to you upon successful registration (or you can save it from within the browser window that loads). This Install Key file can be used to license MC on your other computers. To do so, execute the Install Key by double clicking on it from Windows Explorer or the Finder (after you have installed the correct version of MC).

Each individual install key (mjr file) is only good for 14 days. After that, to generate another Restore again. You can Restore your license, and generate another Install Key up to ten times per rolling calendar year.

Problems?

• Use Copy and Paste to enter your Registration Code, to avoid mistakes.
• Browsers can sometimes cause problems. For example, when you download the Install Key, Opera renames the .mjr extension to .exe and this will not work. Try another browser if you have trouble with the mjr file. IE and Chrome are reliable.
• When you copy and paste, make sure there are no leading or trailing spaces in the Registration Code.
• You can view the license status under Help > Registration Info.
• Make sure that the version and OS of the license and the version of the installed program match. You cannot use an MC18 license with MC19, for example, nor a Windows license on a Mac.
• Verify that your system date is set correctly.
