This getes me back to the other part of the question, is anyone currently
working on this? I know people at CodeWeavers supposedly were working on
getting the various mutations of InstallShield working, this error seems
to be pretty common across all InstallSheild v6 based installers I've seen.
I had also heard there was progress getting Alice install working at
TransGaming, is that InstallSheild v6 based?

Unfortunately I've hit crunch time at work so all non-work related efforts
have been paused. Hopefully in a week I'll get back to trying to figure out
what was up with the 0x80070008. I think it my just be because I need to use
native com dlls as well as the ole ones, but that is pure speculation at this

As for doing the 10k+ lines of coding myself, I have experience in
(de)marshalling and network coding, spent many years doing it, it's more a
matter of available time and learning the com wire protocols, neither of which
are currently available to me. Here's to hoping someone is already working on
it ;).
