A Master License will work on Windows, Mac, or Linux. If you use just one of those, you can purchase licenses for each of these separately.
You can upgrade a single OS license to a Master License of the same major version for a reduced price.
If you have never purchased MC, just download and install it, then purchase from within the program. Please Double check the price before accepting. Do not continue if the price is not correct.
Recover Your License
- Old versions of MC can be found in the Old Versions article. Your version must match your license.
- You can restore your license by using the Registration Code you received by e-mail from buy-button at jriver. You can enter it on the Restore Page.
- If you can't find the e-mail, you can use option #2 on the Restore Page to ask our license server to e-mail you your licenses. You can also change your e-mail address there if necessary.
If you have any questions, please post on Interact.
