Thank you for contacting us about this. It’s likely that VC++ 2013 redistributable is not installed in your system. Please refer to this post for more information on how to resolve that:

How do I resolve 'FileNotFoundException: Could not load file or assembly 'PDFNet.dll' or one of its dependencies' [64-bit and .NET 4 specific]?

" or one of its dependencies." Most likely this is the VC++ runtime dependency. For PDFNet versions 7.0 and older, this is the VC++ 2010 runtimes. Starting with PDFNet 7.1 it is now the VC++ 2013 runtimes. https://www.pdftron.com/documentation/windows/info/prerequisites/#net-framework-40+ Please download the installer from MS and install on the target system, or add to your installer/deployment system to automate.
