Win32: Error: Library not registered. (0x8002801D) when using AddHostObjectToScript

[omerbalash]

Hi all

I created an implementation IDispatch to be used with AddHostObjectToScript, i am able to fetch an instance using CComCoClass::CreateInstance without issues, and i can verfiy in C++ that the object is valid and i can invoke its methods. When i add it using AddHostObjectToScript everything appears to be ok (no errors) and the root object i.e. chrome.webview.hostObjects.sync.test is available but when i try to call any of the methods of the dispatch i get
Error: Library not registered. (0x8002801D)

I tried both sync and async conventions but both show the exact issue. This same code worked for me a year or so back and this issue has only recently started. Could someone please suggest what could be wrong? Sadly i see no other indication of error and could find no documentation on the matter.

Thanks,
Omer
