View Full Version : Installer not upgrading previous version even with new Product Code and Upgrade Path

I am updating an existing InstallShield Express 2014 project and want the installer to automatically uninstall the last version created with the same project, i.e. to do a major upgrade.

I have updated the version number, changed the product code and added an upgrade path with Min Version = Yes, Max Version = Yes and the unchanged UpgradeCode.

However, when I build and then run the installer, it fails to remove the old version of the product and offers Modify, Repair, Remove options instead.

Any hints as to what other steps I need to take to complete a major upgrade?

After some more research and experimentation I found the answer, I needed to update the package code which wasn't in the same place in the InstallShield UI as in the older version I had used previously. I wrote a blog post on how to set up a major upgrade in InstallShield Express here (http://www.sliqtools.co.uk/blog/technical/installshield-express-major-upgrade/). I hope it helps anyone with a similar problem.
