AI image upscaling was not originally included in the permanent version, it was only a plan as a benefit for users of the permanent version. No watermark version available only Windows Store version ， Nero platinum 365 subscription and AI Image Upscaler standalone version. For permanent versions, there is always a Nero log in the lower right corner. (trial version is filled with Nero logo).
To avoid misunderstandings, we will remove the AI image scaler app in future permanent releases.
If you want the Pro features without the Nero logo, can purchase Nero Platinum Suite subscription version, or Nero AI Image Upscaler standlone subscription from Nero offical web(https://www.nero.com/enu/products/AI-image-upscaler/) and Windows Store(https://www.microsoft.com/en-us/p/nero-ai-image-upscaler-365-image-enhancement-by-ai/9n346n9mmkd9?activetab=pivot:overviewtab)
Temp solution is manually add a blank border below the image and manually crop the logo after zooming in.
