Upgrading to v4.2

If you are trying to upgrade from version 3.x please follow the instructions here. Otherwise read the steps below.


If you have internet access, go to client "Help" menu, select "Check for version updates" and follow the instructions. In case the update is not detected, open File/Preferences/Install/Update and select radio button to include "compatible minor increments". Otherwise download and install the client on top of your current installation.


To be on the safe side, keep a copy of current logFaces server installation directory before you proceed with updates.

If you have internet access, go to admin/status page and check for updates, the process is automated and takes only a few moments.

Otherwise follow these steps:

  • Stop logFaces server if running
  • If using archived distribution, unzip it over the current installation, the configuration is preserved.
  • If using installer, let it handle the update. Don't register as service on Windows.
  • Start logFaces server

MongoDB users - Sometimes during updates you may end up with more than one MongoDB driver in /lib/dbdrivers folder. This may happen if you manually place the driver there. To prevent surprises, make sure that there is only single dirver jar in this location.
