Hello,

I'm not sure if this is a Matlab problem or a Windows problem (or a me problem)! I'm trying to run Matlab 2011b on a Windows 7 64 bit machine. I get the error described in this page: http://www.mathworks.com/support/solutions/en/data/1-9VQS9L/index.html?product=ML&solution=1-9VQS9L , thus java is not enabled.

I have attempted the solution in this page: http://www.mathworks.com/support/solutions/en/data/1-1812J/

Unfortunately the solution is not working. I created the MATLAB_JAVA variable in Windows to where the rt.jar file is. I still get the same error message, and it looks like the MATLAB_JAVA variable that I created isn't "sticking", and it refers back to a different directory that does not exist. I've updated Java on this computer to the latest version.

Does anyone know how to solve this?

Thank you!

Ok, I updated the Java to the correct (?) 64 bit version, which eliminated the warning first mentioned above. Now I get the message "Warning: Unable to load Java Runtime Environment. The specified module could not be found." Where do I go from here?
