If you purchased PDF Studio through the Ubuntu Software Center, you will receive a license key to activate PDF Studio from Ubuntu. Once PDF Studio is activated, it will run in full mode, not in demo mode, and will not add watermarks to documents.

Note: The license keys provided by the Ubuntu Software Center are currently for an outdated version. After purchasing send us a copy of the license Key received from the Ubuntu Software Center as well as the purchase confirmation and we will upgrade your license to the latest current version at no cost.

PDF Studio license key purchased through the Ubuntu Software Center can be found in three places:

  1. At the bottom of the Ubuntu Software Center receipt emailed to you during purchase.
  2. In the online copy of your Ubuntu Software Center receipt at: https://pay.ubuntu.com/payment/ . Click the icon in the ‘Receipt’ column next to your purchase.
  3. In your Ubuntu Software Center subscription details. Go to https://software-center.ubuntu.com/subscriptions/ , click on the title you want the key for, and the key should be displayed in the middle of the page.

If you can not find the key that was included on your receipt, please contact Ubuntu Software Center support to let them know. Support for purchases is available from pay-support@canonical.com.

If you are still having issues finding your license key, contact us.
