Under Windows, the T4 GUI installer indicated that the installation completed OK, but the default behavior modules and the low-level supporting processes are not installed. How do I recover?
This scenario can be caused by a previous failed install or a previous failed uninstall of the T4 agent or ETEWatch application.
The GUI installer posts a message similar to the following after it installs the T4 agent on under Windows:
Return code 0 normally means that the agent installed OK. However, during installation, existing registry entries may cause the installer to incorrectly determine that certain components have already been installed. Consequently, the installer skips installing these components.
After T4 installation completes, the following subdirectories of the C:\IBM\ITM\TMAITM6\cat\Mgmt\Collector directory are missing:
TC -- Normally contains the default behavior modules.
Sds and Collector -- Normally contain low-level supporting processes.
Also, the installation logs may not indicate that anything unusual happened. Review the installation logs in the following directory:
The first inclination is to run the following command to uninstall the CAT (Client Application Tracker), and then uninstall the T4 agent from the Windows Add/Remove Programs dialog.
Refer to the following section in the ITCAM for Transactions Installation and Configuration Guide:

uninstalling the Client Response Time agent
