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?
AFAIK, no one is actively doing this. We're working hard on the installers, including everything up to the point of actually diving of the COM/DCOM cliff.
