HowTo? Run A Custom Action Just After Uninstallation Begins

Hello guys, I need to be able to fire off a custom action as soon as
the user begins an uninstall (before files are deleted, etc...).
VS2008 shows four options to choose from..."Install", "Commit",
"Rollback" and "Uninstall". Unfortunately custom actions in the
"Uninstall" phase do not fire until AFTER the uninstall has completed
(according to Microsoft's documentation). So, how does one get a
custom action to fire just BEFORE the uninstall?

Are you sure?
The only reference I could find in the help file is this:

Uninstall
Custom actions placed under this node will be executed at the end of the
uninstall phase of installation, which occurs when an application is
uninstalled.

This is extremely badly worded and ambiguous. It does seem to imply that the
custom action is performed after the uninstallation, but I'm not sure if
that is what was intended by the 'author'. Have you tried it? I would be
very surprised if the custom action were to execute after the files were
deleted. If you are using an installer class, the DLL containing this must
still be available for it to call into, so clearly it cannot have been
deleted yet.

You were right. It is extremely badly worded. The CA gets called at
the beginning of the uninstall phase and not at the end.
