Is the uninstaller app in the application folder? If so, then that is your problem. That is probably why there is an add/remove programs feature in Windows. Apps cannot delete themselves, although they should be able to move themselves to the trash, and then delete the folder they were launched from. I could be wrong on that point tho'.

We have to do that because of course an app can't delete itself.  The copy has the UI that the user clicks to start the uninstall.
