Phil,
Just one catch.. this (ver 1511)? is a new re-install. 1507 was the first Win10 release (2.1)? so this is all ready back to the beginning : -).?
Trying to get the update via another means and I am at 5% of that as I type this on other system.
Probably a product key issue as it was an update from Win7 to Win10 ( when it was a ' FREE ' update, 2016). Unfortunately the HDD died last week.
I replace the drive with an SSD and now dealing? with the re-install.
Marc.
