FIX: Uninstalling Zetafax Client does not remove Zetafax Outlook Addin from all users



ID: ZTN2067

This Zetafax technical note applies to:

  • Zetafax 2014


On some multi-user systems (typically Windows Server 2003 Terminal Services machines), when uninstalling the Zetafax Client Applications that have had the Zetafax Outlook Addin enabled, the Outlook Addin is not removed for all users of the system.

An error may appear when starting Outlook relating to installation of an Office customization:


The Zetafax Client installer has an issue with certain older OS configurations that prevents it from removing registry keys associated with the Zetafax Outlook Addin for users, particularly in a Terminal Services system.


This fault was corrected in a hotfix, which is available by contacting Equisys Technical Support and quoting the technote number ZTN2067. This hotfix requires the addition of a Group Policy script to the affected machine.


This behaviour was corrected in the hotfix detailed above.
