'RFA8_NET150_x64.dll' requires Microsoft Visual C++ Redistributable for Visual Studio 2017. You can get this from https://visualstudio.microsoft.com/vs/older-downloads/. It is under the Redistributables and Build Tools tab.

Hi @RSuryasetty,

Does this previous discussion of a similar issue help?

Also may be worth checking if .Net framework is installed on deployment machine and is the same version?

@Zoya.farberov, we have added the dll as shown in that private discussion. Screen shot here.

Hello @RSuryasetty,

Will you be able to run one of the simple consumer examples, that came with RFA.NET SDK, on the new server machine?

This may enable you to collect more information, and to differentiate between a machine setup-related and app-related type of issue.

RSuryasetty

Yes, this fixed the issue. thanks for the solution.
