Telerik Document Processing is separate license from Telerik UI for WPF ???

[Bill]

I have Telerik UI for WPF and used RadPdfViewerControl. I noticed the below message on UI when rendering PDF file. Is this not included as part of Telerik UI for WPF ? Do I need to purchase a separate license for this ? If so, how much is the commercial license  ?

Hello,  Bill,

RadPdfViewer internally uses the engine of PdfProcessing which is a part of the Telerik Document Processing Libraries. It is also included in the WPF license you have and it is installed following the steps for installing the suite with which you've obtained the product.

According to the provided screenshot, the illustrated message indicates that the trial version is currently being used. I would recommend you to have a look at the following KB article which shows how to upgrade to a licensed version if an active license is available for your Telerik account: How to Upgrade Trial to Licensed Version.

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
