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.
