title: Minor Upgrades and patches using WIX
body: <p>We have an installer (msi) for our application. It has references to third party components, system &amp; application dlls coupled together (in same feature). Now we want to create a msi for only application changes (adding &amp; removing features/components). Major upgrade is not an option since we dont want to uninstall thrid party &amp; system dlls. How to achieve this using minor upgrade? I m new to WIX &amp; not able to find better solution. Any help is really appreciated. Thanks in advance !!!!</p>
