title: Matlab fails to validate parallel environment
body: <p>When I run <strong>Parallel</strong> >> <strong>Manage Congifurations...</strong>, Matlab fails to pass the <strong>Distributed Job</strong>, the <strong>Parallel Job</strong> and the <strong>Matlabpool</strong> tests. My system has a double core: Intel Core i5 CPU M520 @ 2.40GHz 2.40GHZ, 2GB RAM, Win7 64bit, Matlab R2011b. After the failed validation, I get the following output:</p>
