I lost my old computer#
If you can still open TexAu on the old computer, remove the device there first. Read Remove a device or revoke your license.
If you no longer have the old computer:
- Email support@texau.com from the email on your license. Ask us to remove your old computer from the license.
- When we confirm, activate on the new computer with the same email and license key.
If the message tells you to wait 24 hours, email us instead. The license stays on the old computer until you remove it there or we remove it for you.

- The exact message from the activation screen.
- Your app version.
