[kepler-users] Kepler 2.3 and MATLAB

[Derik Barseghian]

Sorry this hasn't been easy, and no help from me yet -- I'm trying to get Matlab and a license for my 32bit XP box so that I can try to replicate, hopefully on Monday. It seems to me it should work on your XP box. The last commit message for ptmatlab.dll says it's 32bit:
--------------
r24053 | crawl | 2010-04-29 13:30:49 -0700 (Thu, 29 Apr 2010) | 2 lines

updating matlab jni library for 32 bit windows
based on ptmatlab.cc r57728.
--------------

Interesting to hear about the error on 64bit AMD, sounds like we have an (additional) problem there.

Can you send your PATH?

From what I can find on the web, that  "The operating system cannot run %1" is a generic error that implies a path issue. Anything I can check regarding the Kepler classpath or libraries come to mind?

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.
