I lost my license key

You can usually find your key yourself. If you cannot, support can send a replacement key.

Find your key#

  1. Search your inbox for the email "Your TexAu Desktop key". Check the spam folder too.
  2. Search with the email address that you used on the AppSumo redeem page.
  3. If TexAu is still activated on your computer, click "Settings" in the left sidebar, open the "Account" tab, and find the "License" section. It shows the email and part of the license key.

Ask for a replacement key#

Email support@texau.com from the email on your license. Include your license tier.

Do not send your passwords or payment details.

Before we send a replacement key, AppSumo must confirm your license and the email on it to us.

When support sends a replacement key, the old key stops working.

FAQs#

Can I enter my AppSumo code in the app? No. The app accepts only license keys in the format XXXXX-XXXXX-XXXXX-XXXXX. Read Redeem your AppSumo purchase and get your license keys.

I no longer have access to the email on my license. While the AppSumo deal is running, we can change the email on your license. Email support@texau.com with proof of your AppSumo purchase. After the deal ends, the email on a license cannot be changed.
