Deployed Patches Appear As Missing In Protect After Subsequent Scan

Version 9


    Previously deployed patches show as missing in Protect.



    This issue occurs when Protect cannot locate the patch you installed. It is possible that the patch is delivered to the remote system, but is never executed. This may happen if the scheduler does not start the deployment. This can also happen if the patch requires a reboot to fully install, and a reboot has not been performed before running another scan.




    Before you begin, ensure your system is rebooted after the patch is installed. Patches that require a reboot after am installation are not fully installed until a reboot takes place and they will appear as missing. Do not rescan before deployment is complete, or patches may show as missing.  Perform another scan after the system has been rebooted.


    To determine whether the batch file or patch is executed, go to C:\Windows\ProPatches\Install folder on the target machine. Look for an associated .BAT or .HIS file with a similar time-stamp. The .BAT file is renamed with a .HIS file after deployment is complete. The presence of the .BAT files indicates patches have not yet been executed, or finished executing. To manually test this on the target machine, launch the patch file manually and follow the prompts. Note errors that are displayed during the installation process and inform Technical Support accordingly - screenshots may be useful.


    If the rescan scan does not result in showing the patch as installed, it is possible you are experiencing a different issue. To further examine your case, contact support ( You should have the following information ready before contacting Shavlik Technical Support:
