Question 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.
To create a small update, use the patching technology found in the Patch Wizard of Wise for Windows Installer Professional, Wise Package Studio, or Wise for Visual Studio .NET.
Required modifications for a small update from the Windows Installer SDK: Note: The Windows Installer SDK is accessible from the Windows Installer Help menu.
