Unable to cast COM object to interface type #689

Open skandl opened 4 years ago

skandl commented 4 years ago

I am trying to use edge.js to make calls within a Node application to invoke methods in a third party COM DLL. I know depending on the way the library was created (example), there are limitations but I am new to working with them.

When I invoke a method in the DLL, I get the below exception. Any ideas if this could be a limitation of Edge, or the library itself, or something else entirely? 

Error: Unable to cast COM object of type 'System.__ComObject' to interface type 'Foo.Internal'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{FA3FF6A2-BC84-4709-9301-BC8216845F4E}' failed due to the following error: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

(Note I replaced the library interface type above)
