Followed msconfig instructions. Runtime error persists. I re-booted in "selective startup" by mistake on one occasion and I think it was on that re-boot the runtime error did not show. Meantime I had some problems with IE 11 - would not launch websites from bookmarks, re-installed IE 11 now working normally.
