Thank you for your post above. We’ve not seen this error previously. The ‘TPH’ mentioned could be either a Formativ component, or a third party component.
Could you try uninstalling Formativ Runtime, then re-installing. If the problem persists, please send the Formativ Configuration information to firstname.lastname@example.org. You can access the configuration information from the main GroupWise menu: Help | About Formativ. When the About box appear, select the configuration tab. Press the ‘Copy to Clipboard’ button, then paste the contents of the clipboard into a message body.
