Failed --Retrieving the COM class factory for component with CLSID ....
PROBLEM:
When you run the .net Code in X64 Environment you will get the following error message.
" Failed --Retrieving the COM class factory for component with CLSID ...."
E.g. in CMS Export / Import server side .net code = "ExportSiteContentIncremental(...) Failed --Retrieving the COM class factory for component with CLSID {CA0752B3-021C-4F99-82E3-2C0F19C5E953} failed due to the following error: 80040154."
WORKAROUND:
The possible workaround is modify your project's platform from 'Any CPU' to 'X86' (in Project's Properties, Build/Platform's Target)
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.
