Activate your licence

Paste your key into Lynx to turn on Pro — and move it to a new computer.

Where’s my key?

Right after checkout, your licence key is shown on the thank-you page, and it’s emailed to the address you bought with. Lost the email? Get your key again — we send it to that address, any time.

Activate in one click

In the email, choose Activate in Lynx. Lynx opens, asks, and turns Pro on. (The thank-you page has the same button.)

Activate by hand

  1. Open Lynx and go to Settings › Licence (⌘,).
  2. Paste your key.
  3. Choose Activate.

Pro turns on straight away.

One computer at a time

A Pro licence works on one computer at a time, Mac or Windows. If you activate it on a second computer, Lynx there tells you it’s in use elsewhere and offers to move it.

Moving to a new computer

On the old computer, choose Settings › Licence › Deactivate, then activate on the new one. If the old computer is gone, write to us and we’ll free the licence so you can activate it again.
