AlteryxAPISample C# application is failing with missing DLL error

[dotnetravi]

I am trying to run the AlteryxAPISample application, but it is failing with the below error. I have copied the Base.dll file to the execution directory but still it is failing. 

System.DllNotFoundException: 'Unable to load DLL 'Base.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)'

Few additional inputs on this issue, C# application using the Altreyx version 2018.4 DLL reference is working without any issues. Issue is with the latest Altreyx version (2023.1.1), not quite sure if I am missing any prerequisites.

Please help me in resolving this issue. Thanks in advance.

Which application are you running (ie where did you find it?) my hunch is it's no longer maintained...

Thanks for your response. I am using the sample code given in APIs\SampleCode directory.
