9999    Invalid .EXE caused by RDD unavailable at startup

     Explanation:  The runtime system has failed to detect an RDD loaded
     in an application that requires one.

     Action:  Check third party .LIBraries for compatibility and version.
     Check link script and order.  Look for missing RDD .LIBrary or .OBJ
     files.  The .EXE may be invalid.
