To apply Sync Home, Sync Family or Sync Business license follow the guide:
On Windows and Mac simply double click on the downloaded license key, or right click and pick to "Open with Resilio Sync". Another way is to open Sync UI, go to Menu -> Licenses -> Apply new key, select the downloaded license key.
In Sync using WebUI (Linux , NAS and Windows service):
1. Download the license key file.
2. Open it in text editor.
3. Copy the chain of symbols and paste it into the manual connection box ("+" -> Enter key or link).
4. Click 'Next'.
Note: if you are using Sync 2.0 - 2.1, be sure to add btsync:// before the chain of symbols.
To activate license on a headless computer, run the commands
Linux: ./rslsync --license /path/to/Sync_Home.btskey
Windows: "Resilio Sync.exe" /license C:\path\to\Sync.btskey
Share a License Seat
Once you've applied the multi-seat Business license key, share the remaining seats with others. On license Owner go to License menu and click to e-mail or copy the link and send it to other device.
- 'Copy' - this will copy license sharing link to clipboard. You can then manually paste the link into an e-mail, text file, message etc which will be sent to another person.
When a person receives the link, they need to paste it to "Manual Connection" field in Sync. License Owner will get request for accessing the seat:

By hitting approval, you will grant one of your seats to that person.
Remove a License or a Seat
To remove a license go to Licenses menu and click "Remove license" button. Note, removing Business license from License Owner does not remove it from License Users. Same way - removing a shared seat will not affect other License Users and License Owner
