Successfully stopped the configuration of SharePoint Products.

Configuration of SharePoint Products failed. Configuration must be performed before you use SharePoint Products. For further details, see the diagnostic log located at [LOCATION OF LOG] and the application event log.

This KB article describes the cause and and solution for this issue. The suggested solution is to clear Windows SharePoint Services configuration cache. Unfortunately, this may not work in most of the cases. If it doesn’t work, there is another workaround. This is by setting the ‘command-line-upgrade-running’ configuration property to ‘No’ and running Configuration Wizard again. Entire steps are given below.

  1. Open command prompt as administrator.
  2. Type in the command: stsadm -o setproperty -pn command-line-upgrade-running -pv No
  3. Restart IIS and SP Timer
  4. Run configuration wizard: psconfig -cmd upgrade -inplace b2b -wait –force

The entire steps has to be done in all the web and app servers.
