Bruce Davies Posted July 12, 2023 Report Share Posted July 12, 2023 (edited) Hi, I have PDF Pen license starting with PPEN12... I have just been notified that v13 is available and is possibly a paid upgrade, but when I input the license code accepted by the app, your website says it is not recognised. Please advise as I cannot move further... Edited July 12, 2023 by Bruce Davies typo Link to comment Share on other sites More sharing options...
Official Nitronaut Leslie V Posted July 12, 2023 Official Nitronaut Report Share Posted July 12, 2023 Hello @Bruce Davies Thank you for posting on our Community Forums! Sounds like you are using the upgrade widget for our product for Windows, not the one for Mac. To upgrade to the latest version of Nitro for Mac, Download version 13. Launch it. The app will notice your previous version. You can click on "Buy an upgrade license" for upgrade pricing. Go through the screens to purchase the upgrade to version 13. Complete your purchase and version 13 will register with your new license. You will also receive an email of the new license for your records. Please let me know if you have any questions.
