I’m trying to run zoom\_sdk\_demo from c#. When I execute ZOOM\_SDK\_DOTNET\_WRAP. ZOOM\_SDK\_DOTNET\_WRAP.CZoomSDKeDotNetWrap.Instance.Initialize(param); in app.xaml return SDKERR\_UNINITIALIZE. CZoomSDKeDotNetWrap.Instance.GetAuthServiceWrap(). SDKAuth(param); it systematically returns SDKERR\_UNINITIALIZE. I got app\_key and app\_secret for JWT and OAuth and in both cases it works the same. ---

Yes, using the latest wrapper from the Zoom Marketplace, 1. Copy the “ **h** ” folder in the **Windows SDK** into the **C# wrapper** folder please explain more about C# wrapper folder. where it is located.? ---

Hey @myclassboard, No need to copy anything over from another folder. On a fresh download of the wrapper it should be runnable. Thanks! Michael ---
