Installation went fine until I had a momentary Intranet stoppage while updates were being downloaded… After starting again,Progress bar showed “Please Wait” After a few hours, it still said wait, but a red line under the progress bar showed Debug499. From Google, this is related to servers. I’ve repeated this several times. Maybe server overloaded? Maybe I just need to try again and again"
I also installed latest two Windows updates and disabled Defender.
