I'm working on a new version of a vB4 Mod my company released a while back and I want to make the upgrade process seamless. Currently, If I try and add the new package with the old one still there I get:
Quote:
Product 'Janrain Engage' is already installed and you did not specify that this product may be overwritten/upgraded.
|
If I uninstall the old version and install the new version, my uninstall scripts remove all the custom database entries so user data and settings disappear.
How can I make my product upgradable? I can't find documentation on this.
