I have two machines on my network that get this error when I try to start a scheduled backup task ( E00640067 - Failed to run task). The funny thing is I can run a manual backup no problem, however when I create a task and try to run it I get the error. The user that Acronis is running under has admin right on the clients machine. I'm using version 9.1. I have tried uninstalling and reinstall with no luck. This happens on only two clients.
