--- Comment #6 from Nikolay Sivov bunglehead@gmail.com --- Thing is, I think what happens is that context creation fails because of inaccessible dependency. So it does not matter if comClass elements are parsed correctly, they won't be used if context wasn't created. You can easily verify with +relay log, looking for STATUS_SXS_CANT_GEN_ACTCTX status from RtlCreateActivationContext().
