Hello,
This is very odd, I have checked and the silent install string is still part of the latest version. Could you please send over the log files listed below from one of the affected end user devices and we can take a look.
%WinDir%\CCM\Logs\AppDiscovery*.log
%WinDir%\CCM\Logs\AppEnforce*.log
%WinDir%\CCM\Logs\AppIntentEval*.log
%WinDir%\CCM\Logs\CAS*.log
%WinDir%\CCM\Logs\CIAgent.*log
%WinDir%\CCM\Logs\DataTransferService*.log
%WinDir%\CCM\Logs\PatchMyPC-ScriptRunner.log
This may be found in the %ProgramData%\PatchMyPC\ if the Install was initiated by the user from Software Center.
%WinDir%\CCM\Logs\PatchMyPC-SoftwareDetectionScript.log
This may be found in the %temp% of the user who clicked ‘Install’ in Software Center if it was an ‘Available’ deployment.
%WinDir%\CCM\Logs\StateMessage.log
%ProgramData%\PatchMyPC\PatchMyPC-UserNotification.log
%ProgramData%\PatchMyPC\UISettings\UINotificationSettings.xml
Thank you!
