I was configuring Software Metering at a costumer when reports seemed wrong. The costumer had already configured metering on Visio,exe which had been running for years, but only 60 installations was reporting usage in the past 120 days out of 540 total installations. I checked maintenance task on the site server and client settings to ensure that the server and clients was configured correct.
I looked into some of the log files on the clients and found this error:
StartPrepDriver – OpenService Failed with error 80070424
