Dear Sir/Madam,,

Hope you shall be with good health.

I am trying to download PTB version which is compatible of 32 bit MATLAB. I am using DownloadLegacyPsychtoolbox function but when ever I run this function it show the following

**THIS SCRIPT IS CURRENTLY NON-FUNCTIONAL. Contact the PTB forum for help if you need old copies of PTB, or check on the PTB website for instructions.**

**Please help me in this matter.**

**Is it possible that I can download the PTB manually and add it to the Matlab path.**

**Your kind and quick reply will be appreciated.**

**Thanks.**

**Best Regards,**

**Naeem**

If you need a recent Psychtoolbox for 32-Bit Windows, i'd recommend using the final version of Psychtoolbox-3.0.12 from June 2016 together with the free GNU/Octave-4.0 for Windows, instead of trying to use a very old version for 32-Bit Matlab. This will work better on modern systems than those versions. You can do that by installing Octave-4 32-Bit from  
  
[https://ftp.gnu.org/gnu/octave/windows/octave-4.0.3-installer.exe](https://ftp.gnu.org/gnu/octave/windows/octave-4.0.3-installer.exe)  
  
then installing GStreamer 32-Bit for Windows (not optional with Octave, instructions under [https://raw.githubusercontent.com/Psychtoolbox-3/Psychtoolbox-3/Psychtoolbox-3.0.12/Psychtoolbox/PsychDocumentation/GStreamer.m](https://raw.githubusercontent.com/Psychtoolbox-3/Psychtoolbox-3/Psychtoolbox-3.0.12/Psychtoolbox/PsychDocumentation/GStreamer.m)), then executing from within Octave:  
  

DownloadPsychtoolbox([targetdirectory], ‘Psychtoolbox-3.0.12’);

  
For a proper 'targetdirectory' of your choice. Choosing 3.0.11 above seems to provide the final 32-Bit Matlab support for Windows and Linux, 3.0.10 seems to provide the final 32-Bit Matlab support for OSX. Needless to say, all these versions are completely unsupported if you run into trouble.  
  
best,
