Unable to execute dll remotely

I am quite new to C# application development.

I have made a C# console application which I execute like this

dotenet.exe <dll_name>

This works fine when executed on the system. But I need to call this remotely. I am doing that through Powershell Invoke Command. But I am getting this error.

System.Runtime.InteropServices.COMException: Retrieving the COM class factory for component with CLSID {D66FBAAE-4150-402F-8581-75D1652D696A} failed due to the following error: 80080005 Server execution failed (Exception from HRESULT: 0x80080005 (CO_E_SERVER_EXEC_FAILURE)). at System.RuntimeTypeHandle.CreateInstance(RuntimeType type, Boolean publicOnly, Boolean& canBeCached, RuntimeMethodHandleInternal& ctor)
at System.RuntimeType.CreateInstanceSlow(Boolean publicOnly, Boolean skipCheckThis, Boolean fillCache, StackCrawlMark& stackMark) at System.Activator.CreateInstance(Type type, Boolean nonPublic) at System.Activator.CreateInstance(Type type)

Please note that I have tried many possible solutions on the net:

• Tried changing target for C# app to x86, this doesn't work as the references to the app are x64

Details about the environments:

• Remote is x64
• Client is x64

EDIT

Please find the source code of the dll. This is used for file conversion to a format.
