problems in SetupPsychtoolbox

Hi~
I adopted PTB local installation. Then I operated through the following steps:

Download and save file “PsychtoolboxCurrent.exe” to “f:\”.
double click and unzip file “PsychtoolboxCurrent.exe” to “f:\”.
Open Matlab;
input “cd('f:\PsychtoolboxCurrent\Psychtoolbox')” to Matlab;
input “SetupPsychtoolbox

However, I got the feedback like this:
"Psychtoolbox does not work on a 64 bit version of Matlab or Octave.
You need to install a 32 bit Matlab or Octave to install & use Psychtoolbox.
Error using SetupPsychtoolbox (line 63)
Tried to setup on a 64 bit version of Matlab or Octave, which is not supported."

My system is 64 bit. I don't know how to solve this problem. If you can repond as soon as possible, I will appreciated for your help.

Sincerely
Li Shen
Simple. You have some very old version of Psychtoolbox wich was only for 32-Bit systems. Get a current one of v3.0.14 from our psychtoolbox.org website.
