#Using the control in a x86 environment

Typical error message recieved after registering the COM component and attempting to run the DemoApp:

Retrieving the COM class factory for component with CLSID {A1FE23EF-03EF-4759-B021-668443C37A24} failed due to the following error: 80040154 (Class not registered)

ROOTCAUSE

The VSS Interop is a managed assembly using 32-bit Framework and the dll contains a 32-bit COM object. If you run this COM dll in 64 bit environment, you will get the error message.

WORKAROUND

The possible workaround is modify your project's platform from 'Any CPU' to 'X86' (in Project's Properties, Build/Platform's Target)
