When you uninstall the tool, do not remove the whole TIB_TCT_HOME directory manually, because by doing this, you will also remove the components of TIBCO Configuration Tool that are specific for TIBCO ActiveMatrix Adapter for PeopleSoft. As a result, when you reinstall TIBCO Configuration Tool and run the tool, it cannot find the components, and fails to launch the configuration. Thus, if you want to uninstall the tool without removing the components for the adapter, follow the instructions in the TIBCO Configuration Tool documentation set.
