When you uninstall an add-on product using the es-guiuninst tool, a summary panel listing all the add-on components that were uninstalled is displayed. When you use this tool to uninstall add-on components in non-English locales, Product Environment is erroneously listed in the summary panel as one of the add-on components that was uninstalled.
Workaround: Ignore the Product Environment uninstalled message. The component was not uninstalled.
