IIRC, one of the P7 SRs removed the main Runtime on uninstall, but it got updated so that it didn't do that fairly quickly.

That's not the same as an external runtime though so I have to wonder whether the original poster installed Poser 6 over the existing runtime or linked to it as an external one which is what anyone wanting to preserve the integrity of their external runtime would have done.
