Wix UpgradeVersion

Question

I\'m trying to do the tutorial \"Checking for Oldies\" from https://www.firegiant.com/wix/tutorial/upgrades-and-modularization/checking-for-oldies/ .

Answer 1

Note that your Upgrade element Id is not set to your UpgradeCode GUID.

From Checking for Oldies:

The Id attribute of the Upgrade tag refers back to the UpgradeCode GUID of the original installation package

Answer 2

Assuming your UpgradeCode guids and versions are correct, you may be cross context; a per user install cannot upgrade (or detect) a per machine install, and vice versa. If you do the install with a verbose log then it may tell you that FindRelatedProducts didn't find one in your install context.
