Hi, Kumar,
I have noticed that the referred assemblies are pointing to an old version:
I have tested loading the provided document with the latest version of the Telerik UI for WinForms suite and it seems to load properly:
I would highly encourage you to upgrade in order to benefit all the introduced improvements in RadPdfViewer during the 5 years gap.
Off topic, please avoid sharing the Telerik assemblies in the public forum. We suggest you use a support ticket. Moreover, it would be handled before a forum thread.
Thank you for your understanding.Regards,

Hi, Kumar,
If you have a valid Telerik license for the respective product, you are allowed to submit support tickets directly from your Telerik account. This tutorial will guide you through the process of contacting the Support team of the Telerik UI for WinForms product in a private discussion.

Kumar,
It would be greatly appreciated if you can provide a screenshot of the checkbox you mentioned for making the discussion private for the Ajax forum. Thank you in advance.
