Are you using MS Windows or are you using Linux? The report above is for MS Windows, but as I scan through it I can see a potential for problems on Linux.

In MS Windows I would recommend checking what your TEMP environment variable is set to.

In Linux, people sometimes point /tmp to a filesystem that has been mounted with noexec as a security measure to reduce the risk of an attacker loading code into a known writable directory and then executing it.

i use windows 8.1, Matlab R2015a,

How can i check my TEMP environment variable?
