How do I create a minor upgrade?
Windows Installer has three methods of updating an application: a major upgrade, a minor upgrade, and a small update. Use a major upgrade to make a large change that warrants a full version upgrade. A minor upgrade is a minor version change such as adding a few new files or making many small corrections. Use a small update when making a few minute changes that do not warrant a version change.
Note the following required modifications for a minor upgrade:
Upgrade Code: Same as previous version
Package Code: Changed from previous version
Product Code: Same as previous version
Version Number: Changed from previous version
Follow these steps to create a new .MSI for a minor upgrade:
To fill out the Upgrades page:
Distribute the minor upgrade as a patch or as a full installation, depending on whether your end users have installed the previous version of the .MSI.
