Mike,

I think that would work out great and I especially like the idea of putting
it in the app.config or machine.config. I did not realize that a choice in
the app.config worked in machine.config that way so I learned something new
from this too.  My one thought here, may be the backup flag should be "true"
to backup and "false" is no backup and the absence of the key is the default
of true so backup by default. This would avoid the kind of negative logic of
saying, yes, do the backup by saying no, don't not backup. See what I mean?

The not backing up choice may also take care of the issue we appeared to
experience on a terminal server the other day when we included the backup
file in the install msi. Not 100% sure but when we made it read-only again
vs read-write the problem went away so I can only guess that in that brief
instance of it backing up someone starting up the application saw it as
"missing" which caused the auto repair feature of the installer to try and
reinstall it. Besides, in this environment we have a lot of people logging
in and out all day and there really isn't a reason to backup the file
everytime someone logs in.

BTW, great thanks for wanting my input.

Jim
