V5 auto-uninstall old version when UpgradeCode is the same

[fxtech]

I'm using the new <Files> element which works well. I have an UpgradeCode. But when I install my .msi more than once, each time a new entry in the ARP (Add/Remove Programs) is created, and I have to remove them all independently, even if the Version string doesn't change.
Some documentation I found seems to indicate that the old stuff should be removed automatically when "upgrading", but thart doesn't seem to be the case.
Is there an example that shows how to properly manage this,so that only one copy of the program shows up in ARM, no matter how many times I "install" it?

Increment the version number and upgrades will work as you expect. Or take a look at MajorUpgrade/@AllowSameVersionUpgrades.

Aha, thanks for that pointer to AllowSameVersionUpgrades!

Curious - why isn't that on by default? What is the point in allowing the same installer to be 'installed' more than once?

I dedicated two Deployment Dojo episodes to this topic. See S1:E5 then S1:E6.

Thanks Rob - very informative!

I think we're going to leave conversations open since they show up better in search. Marking the "Answer" is much appreciated though. Thanks.
