Thank you for your reply. Yes, the fast program was in deselected. All I know at this time is that all of the older chips that I use are programming well. The issue is the 16F19176 which will not invoke the programmer. I want to move to the 16F19176 because of the RTCC and the Vbat backup onboard. This would simplify things. Anyway, I always dreaded updates. Actually, things were much worse than this 2 days ago.
