Thanks so much for the good news!

The bug was in the "SBVAR.DLL" component from 2015. It was just a
coincidence that it happened in this brand new SetupBuilder 2019.2 version.
A typical Ticking Time Bomb scenario <g>.

Thank you for your very cool analysis of the problem (especially the 83 vs.
84 bytes). SBVAR.DLL was the last thing I checked after a very long
debugging marathon <g>.
