I installed v5.7 from the link provided by Admin earlier in this thread. The
Backupper Service seems to have a problem when I shutdown or restart the
computer, causing a lengthy delay. Event Viewer displays the following error message after
restarting the computer: "The AOMEI Backupper Scheduler Service service
did not shut down properly after receiving a preshutdown control” (Event ID 7043). If I first
open the Services menu and stop the Backupper Server manually, the computer
shuts down or restarts normally with no lengthy delay.
