OfficeC2RClient.exe showing dialog boxes to users despite displaylevel=false

The upgrade tools for O365 are not silent enough for our needs and so we have been pushing O365 updates using the OfficeC2RClient.exe.

 $Proc = Start-Process "C:\Program Files\Common Files\microsoft shared\ClickToRun\OfficeC2RClient.exe" -ArgumentList "/update user updatetoversion=16.0.13801.20294 forceappshutdown=false displaylevel=false" -Wait -PassThru


Initially this was working well. Should office be in use, it would silently schedule an upgrade at the next restart of the computer. However, for the last few runs, it's been showing this error message if users don't reboot soon enough after the exe runs.

We do not want to force computer restarts nor want anything to display for our users. A secondary minor issue is that it shows a "Office was upgraded" summary message if Office is not in use and OfficeC2Rclient.exe can do an immediate upgrade. DisplayLevel=False should mean DisplayLevel=False. Microsoft, why does it continue to show errors and summary boxes to customers despite this parameter?

@MikePlichta-1080

Have you made any changes before the first error issue occurres?
Such as Windows updates installation.

Currently, I suggest you locate to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\Updates, then take a screenshot and share with us like the following image.

Please also go to Event Viewer > Windows Log > Application, check whether there is any related record, and then check it's Error module.

The second issue is not reproduced on my test environment, but I received the "Updates were installed" summary message after finishing updating Office.
Please check the Update Channel(s) of Microsoft 365 apps and the previous Version number(s) on users' computers .

Any updates, please let me know.
