Assuming you mean uninstall still, a custom action that calls MsiProcessMessage with INSTALLMESSAGE_COMMONDATA as documented here will do that: http://msdn.microsoft.com/en-us/library/aa370354(VS.85).aspx
Do it as early as you can in the InstallExecute sequence. When I've done this it's not a good UI experience because the Cancel button is initially briefly shown, then disappears when the CA runs, then appears again at the end. I didn't investigate whether this could be improved.
