How do I create a small update with Wise for Windows Installer?
Using Windows Installer technology, there are three types of upgrades: a major upgrade, a minor upgrade, and a small update. A major upgrade makes a large change that warrants a full version upgrade. A minor upgrade is a minor version change such as adding a few new files and/or making many small corrections. A small update is a few minute changes that do not warrant a version change.
