C# Runtime System.InvalidCastException

I'm running a C# Application compiled using visual studio. It get compiled without any error, however at runtime I'm getting following error.

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

************** Exception Text **************
System.InvalidCastException: Unable to cast COM object of type 'System.__ComObject' to interface type 'MSComctlLib.Toolbar'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{66833FE4-8583-11D1-B16A-00C0F0283628}' failed due to the following error: Interface not registered (Exception from HRESULT: 0x80040155).
