Thanks, Christopher. I had already perused the mailing list archives via Google
and just saw references to the same issue without solutions. I confirmed that
the JVM bit width is 32 (Java version 1.6.0_20).
I set up a simpler workflow with just a SDF director, MatalbExpression actor and text display
actor, and configured the expression: "rand(100,1);", but I got the same error. Here's
the trace from the first time it was invoked, which yielded a little more info as you indicated,
specifically "C:\Program Files\Kepler-2.3\common-2.3.0\lib\ptolemy\matlab\ptmatlab.dll: The
operating system cannot run %1". Hope that points to a specific issue.
Thanks.

complete stack dump:
ptolemy.kernel.util.IllegalActionException: There was a problem invoking the
Ptolemy II Matlab interface.
The interface has been tested under Linux, Mac OS X, and Windows.
The interface requires that Matlab be installed on the local machine and that
the ptmatlab shared library available.
* Under Linux, you must have the LD_LIBRARY_PATH environment variable set to
include the directories that contain libmx.so and libptmatlab.so.
* Under Mac OS X, you must have the DYLD_LIBRARY_PATH environment variable set
to include the directories that contain libmx.dylib and libptmatlab.jnilib.
* Under Windows, you must have your PATH set to include the Matlab bin/win32 or
equivalent directory so that libmex.dll is found and the directory that
contains libptmatlab.dll. In addition, if you are running under Windows from
the Cygwin bash prompt, then you must start Vergil with the -jni argument:
$PTII/bin/vergil -jni. For details, see $PTII/jni/package.html.
Refer to $PTII/ptolemy/matlab/makefile for more information.

Hi Wade,
I don't think I have a WinXP installation at hand, but I was able to run the
MatlabExpression demo under Windows Server 2003 with a 32-bit JVM from a clean
install of Kepler-2.3. Windows Server 2003 is fairly similar to XP.
To determine the bit width of your JVM, start up Kepler, go to Tools -> check
settings and look at the value of
sun.arch.data.model = 32
When I start a dos shell (Start->Run->cmd), I can start matlab from the command line, which works for you.
