When the Parallels Client update is being installed, it would be very helpful if a progress bar would display on the screen. Depending on the computer, an update make take a few minutes. Normally, the computer will restart once the update is installed. We have told our staff this, but they don't always remember and someone will inadvertently turn off their computer before the update is finished. When this happens, they have to download the full installation file in order to be able to connect to Parallels.
