Hi,

I am using MatLab and I would like to install mex using

mex -setup

But, an error appears :

 C:\PROGRA~1\MATLAB\R2012A\BIN\MEX.PL: Error: MEX failed to create a temporary 
      directory.  The directory "C:\Users\ABDELK~1\AppData\Local\Temp" 
      defined by the environment variable %TEMP% either does not exist  
      or is not writable.  Consider changing %TEMP% to a writable directory,  
      for example "C:\temp".
