[wix-users] Same version upgrade adding 2 entries in ARP

[Edwin Castro]

The Windows Installer engine, MSI, is in charge of actually upgrading your
application. The Windows Installer engine defines a MajorUpgrade in a very
specific way, ProductCode must change and ProductVersion must change and
ProductVersion ignores the fourth version component. If the ProductVersion
does not change, the by definition you do not have a MajorUpgrade. You may
have a different type of update with different rules but it will not be a
major upgrade.

WiX bundles do support all four version components so you could use a
bundle to wrap your msi. You'll a custom bootstrapper application to
support same version upgrade, I think. At the msi level, which is hidden in
ARP, you still need a ProductVersion that changes (first three version
components) but that entry is hidden and not visible.

I'd caution against upgrading without changing any versions. That is a
configuration management nightmare independent of whether you can implement
it or not. Customer says "I have version X.X.X.X installed and feature Y
does not work" but which version X.X.X.X do they mean since you have
released multiple of that version? Better to give everything a new version
to ensure identifiability.
