I want to write an msi using WIX which would check if there is previous version of the product installed. If yes, then it has to compare the version numbers and prompt the user to either Upgrade, Overwrite or Stop the installation. Though, I don't want to do a major upgrade which would upgrade it by default. Rather I want the user to select the options from a UI. Please let me know of any way to achieve the same.

What does "overwrite" mean? You can use UI to prompt the user before performing a major upgrade.
