Comment (by pospeselr):
Ok so the crash we're seeing on 64-bit windows is an exception raised by
combase.dll!ObjectStublessClient. Essentially that method bails out if
it's found the stub was built with midl.exe older than version 5.2.202, so
the fix is to just update the version constant inserted by widl. I've
tested on 64-bit windows with NVDA and Tor Browser now transitions from
the network dialog to the main browser window without crashing.
