OfficeC2RClient.exe get progress state

Hello,

I would like to implement Office updates into our scheduled maintenance automation. Therefore, using OfficeC2RClient.exe and a CMD should be a convenient way to achieve this. I'm using the following parameters:

"C:\Program Files\Common Files\microsoft shared\ClickToRun\OfficeC2RClient.exe" /update user displaylevel=false forceappshutdown=true

Unfortunately, OfficeC2RClient works asynchron and delivers no state at all. It's just fire and forget. But for monitoring and reporting purposes we need to track the progress and get a final state (success, error, anything else). I've already tried a couple of different things:

• Start as process in PowerShell and check if "OfficeC2RClient.exe" is running
• Check logfiles in Temp directory

Both approaches are not optimal and have some downsides.

Do you have any idea, how to achieve this in the most simple and consistent way?
