I never thought of that. On your suggestion I tried showing the GUI, but the results 
were the same.  Except that now the Interactive Services Detection does indicate that 
a process needs some user interaction.  When I try to display the window, I see only 
two black boxes, without any text or buttons.  One of the boxes is probably cscript. 
  The other may hold the answer to the problem, but I cannot see it.

Good idea.  To test this I changed wpkg client to run at shutdown.  Unfortunately, no 
change in the result.

Good idea.  I started process explorer after the install hung. I tried to bring it to 
the front, but it said there were no visible windows to display.

Thanks for the suggestions.
