AxInterop.MapWinGIS.dll is not generated

I’m encountering an issue while upgrading from MapWinGIS v4.8 to v5.3 (64-bit) in my Visual Studio project. After adding MapWinGIS.ocx, I noticed that only Interop.MapWinGIS.dll is generated, but AxInterop.MapWinGIS.dll is missing. Could you assist me in resolving this issue?
