make it seamless to our users. Forcing the user to first uninstall is not

Hey Rich,
If you make your installers set REINSTALLMODE=amus files will be overwritten
regardless of their version. This would let you run upgrades and downgrades
where whomever comes last wins.

Hi John,
Thanks so much for the quick response.
I've seen some comments before about REINSTALLMODE-amus, but there were
serveral cautions around it. In particular, my real install also includes a
few redistributables (msm files).
Guess it it time to research amus further.
Again,
Thank You

Another approach would be to just throw up your hands and say I can't
upgrade from that. Force the users to uninstall before your install.
Then the old version is removed. And the new one comes in cleanly.
Assuming the old one uninstalls cleanly! Very user-hostile however...

I would love to force the user to do the uninstall. But requirements
dictate otherwise.
I am pursuing the suggestion to set the REINSTALLMODE property -- AND see
if I can remove the Redist MSMs from my install. After all, this is
strictly for in-house use.
Thanks for replying!
Rich
On Wed,
You have a majorupgrade element as well as an upgrade element. I'm
not sure why. A single majorupgrade element with AllowDowngrades=yes
should suffice. You should also post the entire log.
