I am trying to run my application on two different systems with same configuration(Intel i5 4th generation Windows 10 Pro), but it works perfectly on one system and another system showing below error. Please guide me to resolve.

Error in Main Method - System.TypeInitializationException: The type initializer for 'DlibDotNet.NativeMethods' threw an exception. ---> System.DllNotFoundException: Unable to load DLL 'DlibDotNetNativeDnn' or one of its dependencies: The specified module could not be found.

Checkpoint

Install Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019
If use FRDN.CUDXXX, install cudnn
If use FRDN.MKL, deploy mkl libs
Check dependencies by using https://github.com/lucasg/Dependencies.
- You can find the missing libraries which be depended on DlibDotNetNativeDnn.

And what did you use framework? .NET framewrok? .NET core? If .NET framework, libraries are not copied to application directory.

@takuya-takeuchi Thank you for your response. I'm using .Net core 3.1 and also installed Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019, but still showing same error.

@prafull-chaure Ok. So check the %USERPROFILE%.nuget\packages\dlibdotnet\19.20.0.20200725\runtimes\win-x64\native/ I don't know what exact version of FRDN. So 19.20.0.20200725 is missing. But you could choice lastest. Then, execute https://github.com/lucasg/Dependencies and open DlibDotNetNativeDnn. You can find the missing libraries.
