Now that your new project is ready for others to use, it is time to distribute it.


linkNative library

Our PDFNetC libraries are self-contained and have no external dependencies.


Please see the .NET 2.0 prerequisites for the necessary prerequisites for the .NET framework 2.0. The VC++ 2008 runtime libraries need to be either installed on the client desktop, or they may be packaged with your application.

Please see the .NET 4.0+ prerequisites for the necessary prerequisites for the .NET framework 4.x. The VC++ 2010 runtime libraries need to be either installed on the client desktop, or they may be packaged with your application.

linkMinimum versions

Be sure to check out the libinfo.txt file in the PDFNetC\Lib folder as it shows what are the minimum version numbers of each language that are required to work with PDFNetC. Note that all the language bindings still need access to PDFNetC.dll to work.


The PDFNetC library you download must match the Java JRE architecture (32 or 64 bit). Link to forum post with more details.

Furthermore the PDFNetC.dll still needs to be available for the PDFNet.jar to access. Link to forum post with more details.


Before trying PHP be sure to read the additional PHP documentation in the PDFNetC/Samples folder.


Read the libinfo.txt file for important information when using Python 2.

Congratulations, you are now ready to deploy the project to your target/customer computers. Please see the demo/trial page for details regarding the demo/trial mode, and related questions.

linkCommon questions/issues

Q: Deploying PDFNet for .NET/WPF: How to resolve FileLoadException due to missing VC redistributable?
A: With newer versions of Visual Studio, Microsoft no longer allows statically linking to the CRT for .NET components. To get everything working, installing the VC++ runtime is not necessary, instead required DLLs (e.g. MSVCP100.DLL & MSVCR100.DLL) can simple be copied into the same folder where PDFNet.DLL is located. There is no dll registration needed. A utility called Dependency Walker can help you to identify which two DLLs are required.

Q: I get an error that says "Could not load file or assembly 'PDFNet.dll'" when using PDFNet for .NET 4.x?
A: The PDFNet x64 library is for targeting frameworks 2.0 - 3.5. Since your building .net 4 or 4.5, you should use PDFNet for .Net 4. If there is some reason to use the .Net 2 assembly, the following article might help.

Q: How do I resolve 'FileNotFoundException: Could not load file or assembly 'PDFNet.dll' or one of its dependencies' [64-bit and .NET 4 specific]?
A: If you are using a direct reference to PDFNet.dll, please ensure that your reference is pointing to the correct version (32-bit vs 64-bit) of the PDFNet dll. Also check and ensure that 'copylocal' is set to true for the assembly reference in the project.
