TestStand as well as other NI products try to be very careful and only uninstall the files that were created by the installer and not any files that are created by the end-user after installation. Even though you would like some or manu of these to be removed, many customers do not like non-original files to be removed. For example, any files in the User directories or the Cfg directories should be left alone. I know that some of the TestStand installers before 3.0 incorrectly remove the
\OperatorInterfaces\User directory.
Your only option is to just manually delete the contents under the installation directory if that is what you want to occur.
