Never Uninstall Resources

The main choices are:

1. If you don't wish to undo anything done during the "install" of an MSI you should have a look at the "No Installation Registration" section.

2. The resources are members of a component, the "ComponentId" can be set to "" so that Windows Installer never registers it. No uninstallation (or "repair") will take place, for example:

   <$Component "NeverRepairedOrRemoved" Directory_="<$INSTALLDIR>" ComponentId="">
       ...
   <$/Component>

3. The resources are members of a component, the "permanent" attribute can be set. It will not be uninstalled however it can be repaired, for example:

   <$Component "NeverRemoved" Directory_="<$INSTALLDIR>" Attributes=^Permanent^>
       ...
   <$/Component>

4. One or more custom actions to perform all the update and removal logic.
