I can actually see two errors here.

One is in the input images.  See the FAQ at
http://wiki.panotools.org/Hugin_FAQ#enblend:_excessive_overlap_detected

The other one is the message "enblend: error: LZW compression is not
available to due to Unisys patent enforcement".  This is an error in the
binary that need not be (the Unisys LZW patent has long expired).

@Matthew: what is the source of the Enblend/Enfuse binaries bundled with
your Hugin installer?  You need one built against a tifflib that does
support LZW compression for this to work properly.  It is not critical
(it falls back on uncompressed TIFF) but disk space consuming.

** Summary changed:

- An error 1 appeared when Stitching 
+ Enblend bundled with 2011.0.0 Windows binary lacks support for LZW compression.

** Changed in: hugin
       Status: New => Confirmed

** Changed in: hugin
   Importance: Undecided => High
