In Basic MSI projects, how do I prevent my current install from getting overwritten by an earlier version of the product?
I know there are ways to prevent it from overwriting the future versions, but in this case I basicly do not want the earlier version to be able to overwrite my current install. The earlier versions have been released and there is no way to modify them.
Short of AppCompat transforms (which I think Microsoft controls, not you or us), I don't think there's a way to preemptively change an older install not to do this. It's regrettable, but hopefully not a showstopper; how big a problem do you think this will cause with your user base?
Did you get a chance to try if the instructions you linked above actually work?
It didn't work for me. On Step 3a when setting the Minimum Version to the product version of the current project that logically means it doesn't allow any Major Upgrades for this Setup because the version of the older product would always be smaller than our specified Minimum Version to upgrade.
