Major upgrades with WiX
I thought I was going crazy.. I’d built an installer using WiX and set the product version to 1.0.0.1. The plan was that installing a new version would automatically uninstall any old versions.
I then updated the version to 1.0.0.2 and installed the new version, only to end up with two installations.
Turns out that Windows Installer only looks at the first 3 digits of the ProductVersion (as the first Note mentions in the Windows Installer documentation on Major Upgrades) – so twiddling that 4th digit is not going to have any effect.
Here’s a sample .wxs file that works for me:
