Phil,
Thank you for your reply. I do have a couple other things to
mention that I did not know would have an effect. 1) We're doing a
driver installation during this process using Difx. I read of a
potential bug. I would also like to clear up the fact that the installer
is ran initially with administrative privileges. What I mean is that one
application fires the installer. That application is elevated. Therefore
the installer is loaded elevated from the start.
I have tried the ALLUSERS property but I was not able to get any
different result.
Concerning your alternate suggestion, would there be a line to look for
in the log. I reviewed it a number of times but there isn't an error
code that stands out. The installer exits with 0 and reports successful.
Once again, thank your for your time and support
