+/******************************************************************
+WixExitEarlyWithSuccess - entry point for WixExitEarlyWithSuccess
+    custom action which does nothing except return exit code
+    ERROR_NO_MORE_ITEMS. The Windows Installer documentation at
+    http://msdn.microsoft.com/library/aa368072.aspx indicates that
+    this exit code is not treated as an error. This will cause a
+    calling application to receive a successful return code if
+    this custom action executes. This can be useful for backwards
+    compatibility when an application redistributes an MSI and
+    a future major upgrade is released for that MSI. It should be
+    conditioned on a property set by an entry in the Upgrade table 
+    of the MSI that detects newer major upgrades of the same MSI
+    already installed on the system. It should be scheduled after
+    the FindRelatedProducts action so that the property will be
+    set if appropriate.
