Once you have disseminated a major version of your product,
issuing updates to your existing user base can become very
important. While issuing updates, you may want to avoid having
to redistribute your entire setup package, especially if you
have made modifications to only a small number of files.
InstallAware provides true one click patching - just
add "patch references" to your project, which are simply older
versions of the product you are patching against. Then click
the Build Patch button, and InstallAware
will automatically create a patch that updates all
the base packages (patch references) for you.
A patch build contains differential binary updates of the
files changed between the latest version of your application,
and the older versions of your application that you are patching
against. Therefore, patch builds are very small in size and
are very easy to distribute.
