Cool!  This has a chance of working then.

Yes, that appears to be true.  Wine's rpcrt4.dll only
works between programs running in the same Wine
instance.

It's a problem for lots of reasons.  They add up to
this:  this is unimplemented in Wine, and probably
won't be implemented any time soon.

install the DCOM98 update to have any chance of
success at it for now, at least if I read the code
right.
