Thank you for your help and suggestions, Mert!
The problem was indeed with the bundling of the run-time support. Your suggestions made me look more
closely at the Distribution Kit set-up, and I found that in fact, I was still building my Distribution Kit under
Labwindows/CVI version 6.0!
The new installer built under 8.1 was noticeably different, and, lo and behold, had much more depth in the
run-time support. It now executes without error.
Thanks, again. LPR
