Windows Installer provides two main methods for upgrading installations: patching and
upgrading. You can also have the end user upgrade by uninstalling and then reinstalling,
although this method is not recommended.
You can create upgrades and patches for installations using the UpgradeSync tool, Patch
Creation tool, and the Upgrades page.
For information on upgrading, see the following topics in the Windows Installer SDK
Help.
