Terms of License Authorization -
Per the DVDFab License Agreement, a Single-Computer license is allowed for using on only one computer or mobile device. However, there are circumstances when you might need to use DVDFab on two or more computers/mobile devices. To address this matter, we offer you the option to buy Multi-Computer License to authorize your DVDFab on multiple computers, and the Multi-Mobile License to authorize DVDFab (Downloader for now) on two or more mobile devices.
1. As of now, Multi-Computer License works on DVDFab 12, Passkey 9, Player 6 and Downloader.
2. The validity of the Multi-Computer License stays same as the validity of your original license.
3. A new computer can be authorized anytime via DVDFab client, and conversely, an authorized computer can also be deauthorized anytime.
4. When deauthorizing a product (e.g. DVDFab 12) on a computer, all the other products (Passkey 9, Player 6 and Downloader) will also be deauthorized on that computer.
5. If you need to deauthorize a computer/mobile device that you can no longer access, you need to deauthorize all computers/mobile devices at DVDFab Member Center. However, you can only do that once per year.
6. When buying Multi-Computer License, be clear which platform you want to buy for. You cannot buy Multi-Computer License for macOS if your original license is for Windows platform, vice versa.
