eForms is an optional add-on to FileNet Web Services. Installation of eForms creates a new Open Client preference "IS EFORMS INSTALLED" in the new eForms preference subsystem.
When the preference is set to True (the default when installed), Open Client opens eForms documents in the eForms application.
When the preference is set to False, eForms documents open in the workstation's registered application for XML files. Typically, opening an XML file displays raw XML in the browser.
Uninstalling the eForms software removes the preference.
