Some customers are facing the error 'System.DllNotFoundException' when exchanging library from previous versions to v2.6 or later.
Please see cases below and check if you can resolve your error. If it doesn't resolve your issue with the same error, please contact technical support team directly.
Case 1. Missing libraries
Below three libraries have been added since SDK v2.6. Please find if you added required libraries correctly.
Case 2. VC++ redistributable packages
Some libraries refer other runtime packages which are downloaded from VC++ redistributable packages. Some Windows OS doesn't include those packages by default. Please check if there is any uninstalled VC++ redistributable packages on your platform, and install the corresponding version. You can check missing version on your environment using tools such as 'All in one runtimes' etc.
