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.
