Getting error "Activex Component cannot create Object" while using .NET dll in VB 6 Code

Question

HI, I am deploying a VB6 application on client machine. The Application need to access code from a C#.NET dll. I created a COM object of the .NET dll and used it VB 6 using the side by side versioning (Registration free COM). It is running fine on the development machine but on the client machine it is throwing an error "ActiveX Component cannot create Object"

I created two manifest files one for the VB application and the other one for the C# application. I embedded the C# manifest file in the C#.NET dll through visual studio 2008.

Am I missing some step. Please help me out. Thanks in advance.
