[wix-users] Upgrade Paths in Wix

[Edwin Castro]

One way to understand the <MajorUpgrade> tag is that it produces <Upgrade>
with specific values that represent a "major upgrade". You can author your
own <Upgrade> tags, in addition to <MajorUpgrade>, to add additional rows
into the Upgrade table. You really need to understand how the Upgrade
table, <Upgrade> tag, and <MajorUpgrade> tag work.

http://wixtoolset.org/documentation/manual/v3/xsd/wix/upgradeversion.html
http://wixtoolset.org/documentation/manual/v3/xsd/wix/majorupgrade.html

The key is that you want to specify the minimum and maximum versions for
the allowed major upgrade, and *detect* the versions that you want to
disallow. The Upgrade table is processed when the FindRelatedProducts
standard action executes and its results are stored in properties specified
in the Upgrade table rows. Armed with these properties you can author
LaunchConditions to disallow upgrades when certain versions are installed.
You could instead use the properties to display specific text if you have
authored a UI.
