Automatic agent upgrade still doesn't work in 4.1

[achandra]

All my agents exhibited the same problem:


Product: Viewtier Parabuild 4.1.0 05 Oct 2011 16:14 16252 build 1715
Description: Failed to upgrade agent host at bld-win2.panologic.com:8080 from version Viewtier Parabuild 4.0.56 11 Mar 2011 11:13 15189 build 1893 to version Viewtier Parabuild 4.1.0 05 Oct 2011 16:14 16252 build 1715 . The agent needs to be upgraded manually.

I've had this for many releases now, is there something I can do to fix this rather than always manually upgrading?
