This procedure involves direct editing of the Registry, so should be performed with caution, and if you have:
  1. Been directed to it by Triaster Support.
  2. Been directed to it by a different Triaster Knowledge Base article.
  3. Installed a future release of Process Navigator and then reverted to your previous release, then found that the Visio "Process Navigator" menu is not showing.


  1. Un-install Process Navigator.
  2. Press Start > Run or press Start and click into the "Search programs and files" box.
  3. Type "regedit" and press ENTER.
  4. Press Home on your keyboard or scroll up to the top of the registry and select "Computer".
  5. Press Ctrl+F.
  6. Type "triaster.processnavigator" and press ENTER.
  7. You may find a key like this:

    You may have different version-related sub-keys under the 'InprocServer32' key. The sub-key names you find here should equate to the versions of Process Navigator that have been installed in the past on this machine.
  8. Delete the GUID key that is at the top of the stack, in this case "{19627800-CD77-4888-AB33-962E800B63A6}".
  9. Press F3 to continue searching.
  10. Repeat steps 8 and 9 until there are no more "Triaster.ProcessNavigator"-related GUID keys within the folder HKEY_CLASSES_ROOT\CLSID.
  11. Re-install Process Navigator.
  12. Contact Triaster Support should problems persist.
