PRB: Zetafax Client uninstall freezes with install progress dialog showing



ID: ZTN1916

This Zetafax technical note applies to:

  • Zetafax Client version 2011 and 2012 on Windows Server 2008 R2 and Windows Server 2012


When choosing to uninstall the Zetafax Client from Windows Server 2008 R2 or Windows Server 2012, the installer will freeze at the following dialog:

On opening task manager, there will be an msiexec.exe process using 99% of a CPU core.


This is due to an issue with the Zetafax Client installer when it is being initialised for uninstallation.


The Zetafax Client will uninstall if the msiexec.exe process in the task manager is ended. To do this:

  1. Open task manager.
  2. Go to the processes tab.
  3. Select the msiexec.exe process that is taking 99% CPU.
  4. Click end task and click yes on the confirmation dialog.

This will allow the installer to reinitialise successfully, and thus successfully uninstall the Zetafax Client components.


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