Processing Patch Scan Results Failed


When you look at the Agent Procedure log via Agent module> agent logs option you notice the entry below. Note this would cause patch status page to NOT update correctly as the data has not populated yet. 

           3:01:15 pm 11-Feb-15 WUA Patch Scan 2 System
           Processing patch scan results for <machine_id>  failed.



At some point Zenith Patch Management OR another software/program was installed on the machine



  • Log-in to the machine and locate the ptchscn2.xml on the working directory (e.g. c:\kworking\).
  • Open the file and search for the word: "PROCESS". This will display the process/software that is causing the issue:
    • In this example the component ZPMAuto.exe was found
    • If you confirm that the component is present in the ptchscn2.xml file then perform next steps.
  • Stop the Windows Update service
    • Go to C:\Windows\SoftwareDistribution\DataStore\datastore.edb and rename datastore.edb to datastore.edb.old
    • Note you can also rename the entire folder C:\Windows\SoftwareDistribution to C:\Windows\SoftwareDistribution.OLD
  • Start the Window Update service
  • Run a new Patch Scan

This message on the logs may sometimes be caused due to an outdated version of the Windows Update agent, in which case you would need to update the version:

If in case you may have renamed or deleted the ptchscn2.xml already the file may only contain one line for the machine name - in this case the "PROCESS" name won't be present. However, you can still perform the steps above as the windows file/folder will be recreated once the new scan is performed. 

If this does not help resolve the issue please create a Support Ticket.
