c# - System.Type.GetTypeFromProgID(VisualStudioProgId) return null

Question

Please help me:

Machine 1: win2007(works fine)
Machine 2: winServer 2019 Datacenter(Facing issue)
On Both machines: Same C# code is executed on VS2019 and i want to invoke VS2017

C# Code:

string VisualStudioProgId = "VisualStudio.DTE." + vsVersion;
Type type = System.Type.GetTypeFromProgID(VisualStudioProgId);
EnvDTE80.DTE2 dte = (EnvDTE80.DTE2)System.Activator.CreateInstance(type,true);

1. The code is working fine on machine 1(win2007)
2. On Machine 2(winServer 2019) - Unhandled Exception is reported:
   

I tried to debug C# code further in VS2019 in both machines
Observed different type for Class System Type:

Machine (win2007)(works fine):
Class System Type observed as
Value: {Name = "__ComObject" FullName = "System.__ComObject"}
Type: System.Type {System.RuntimeType}

Machine (winServer 2019)(Facing issue):
Class System Type observed as
Value: null
Type: System.Type
