ID: ZTN1698

This Zetafax technical note applies to:

  • Zetafax 2008


The Zetafax 2008 Server Installation does not complete during an upgrade from Zetafax 2006. The Zetafax Server – Installation Wizard screen remains as follows:


On some systems the _zfrun.exe process is not closed correctly by the installer program even though the upgrade has completed successfully.


Use task manager to end the process manually.

  1. Launch Task Manager (CTRL+SHIFT+ESC) and go the Processes tab.

  2. Click End Process on each of the msiexec.exe processes running under the logged in user (Tomas in this case). That will end _zfrun.exe and close the Zetafax Server – Installation Wizard.
  3. Run up the Zetafax Configuration and continue to add your upgrade license and go through online registration. Add the received registration code and then start the Zetafax Server.
  4. The Zetafax Server will now be running version 2008 and can send and receive faxes successfully.
  5. Continue to upgrade the Zetafax Clients following the advice below:



This has been identified by Equisys as a problem with the software versions given above.
