ok, nice to hear that someone is working on it.

This does the trick for both DCOM95 and DCOM98 (as in the reported
logs). First, I got a message to debug a problem
fixme:seh:EXC_RtlRaiseException call to unimplemented function
wine: Unhandled exception (thread 0009), starting debugger...
but after the debug step I could continue installing DCOM95/DCOM98
without the previous problem.

Well, now I got another error for 'Adobe Illustrator 10', but I'll
report it in a new thread.

BTW, I supposed 'wine-devel' to be a better place than 'wine-user' to
report these problems becuase I'm making these tests after Mike's
question about 'wineinstall'. Please let me know if I should switch to

Yes, I know the native DLLs of 'WineTools' :-) I've no preference for
the WineTools' fake_windows or the Wine one: actually, if I could use
the Wine one it'll be better, so the reason of my tests.

Mmm, I can't find any hit for 'winedll' or 'dcom' in the WineHQ FAQ [1].

Thx, bye,
