Error for setting parallel computing

Hi guys, I’m trying to use parallel computing and follow the steps listed in Prof. Willi Mutschler’s website. I downloaded PsTools and installed it by typing " psexec and psinfo" in the command window.
When I type “dynare mymodel parallel_test”, matlab reports error message: “AnalyseComputationalEnvironment returned with Error Code: 2.2”
Does anybody know how to do with this error? Thanks.

Is that the full message? Code 2.2 is just a warning, namely that you only use 4 out of 12 cores.
