I am trying to install RTC 2.0.0.2 iFix6 on RAD 8.0.1. My RAD already has iFix5 installed on it. Whether I try to update or install, I am getting the following error messages:

It seems like I need to uninstall the previous version, but I can't find an easy way to do that, because it's hard to tell what all parts are coreqs or prereqs of the RTC plugin.

Does anyone have any suggestions?
