Restoring a License
A Registration Code is a permanent license. You receive it via email from buy-button at jriver when you purchase Media Center.
- You can retrieve your Registration Code anytime by using option #2 on the Restore Page. You will receive mail from buy-button at jriver.
- You can also change your e-mail address or password on that page.
- The Registration Code can be used to do a Restore, which installs the license and generates an Install Key. The Install Key is portable and can be used to license additional copies of Media Center, but it expires in 14 days, after which you must restore by using your Registration Code. The Registration Code is permanent.
Version is important.
- Your license must match the installed version of MC and the platform.
- Windows, Linux, and Mac licenses are separate, as are major versions (MC28 and MC29, for example).
- Old versions are available to download.
- Other sites may not be trustworthy.
Restore a license by using your Registration Code on the Restore Page.
- This can be done from within the program, under Help > Install License, or within the startup dialog shown by the trial.
- You must install and run the version of MC that corresponds to your license first.
The Install Key is a temporary, portable license file (.mjr file type), generated whenever you restore.
- The Install Key can be used to apply your license to a particular copy of MC.
- When you Restore, the Install Key is automatically applied to any copy of MC on the computer used to perform the Restore.
- It is emailed to you upon successful registration, and whenever you Restore. Look for mail from buy-button at jriver.
- The Install Key file can be used to license MC on your other PCs (within reason). To do so, execute the Install Key by double clicking on it from Windows Explorer or the Finder.
- Mac and Linux licenses won't work on Windows, and Windows licenses won't work on Mac or Linux.
- You must have the correct version of MC installed first. Your license must be for the correct OS type (Windows, Mac or Linux).
Each Install Key (mjr file) is good for 14 days.
- After that, you must Restore again.
- Using the Install Key does not use a restore.
You can Restore your license, and generate another Install Key up to ten times per rolling calendar year.
- If you use all your restores, please post on the forum. We can reset the count, but this is only done if you have run out.
- Use Copy and Paste to enter your Registration Code, to avoid mistakes. The letter O and number 0 look alike. So do the letters l and I, and the number 1. Make sure there are no leading or trailing spaces in the Registration Code.
- 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.
- 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 MC25 license with MC26, for example, nor a Windows license on a Mac.
- Verify that your system date is set correctly.
- Install and run the version that matches your license, then restore or click on the Install Key
