Yes, as stated in original posts, all was OK after reinstall and updating - or at least the problem has not happened since. I only posted this really to ask if there was a clash between Ofice 365 and KIS, to which the answer appeared to be “YES” - or at least it was at the time (nearly a year ago now). Since then both laptops have updated successfully to the 2020 version, after accepting the recommendation that came in notifications. By the way, this is a much better system for updates. The UK version is now 20.0.14.185(i) but I am not sure of the patch for the one abroad as I am prevented from travelling to it !
