Major upgrade failes when incrementing build number in product version

I change the product and package code when I make Major upgrades but I don't think this is the issue here.
Try looking at the major upgrade settings to make sure the versions you are triggering on are really older versions.
Your previous attempts were actually all the same "version" or installer. Changing the 4th number doesn't distinguish a new version as the number is ignored by Windows Installer. In this description of Product Version, it does not mention the 4th number: https://msdn.microso...9(v=vs.85).aspx
I have read explicitly that the 4th number is ignored but I can't find the link at the moment.

Sounds like you didn't change the ProductCode and thus are doing a minor update. Are you launching the update via setup.exe or by double clicking the msi file?
