For anyone wondering how to do it, I have attached what I did:

1. Create path ‘C:\MyToolboxes\’ in file explorer
2. Getting a hold of the correct Psychtoolbox file for R2015b 32-bit
  1. [SetupPsychtoolbox is no longer supported in 32-bit Windows Matlab?](https://psychtoolbox.discourse.group/t/setuppsychtoolbox-is-no-longer-supported-in-32-bit-windows-matlab/3220)
  2. Psychtoolbox 3.0.11 file: [https://github.com/Psychtoolbox-3/Psychtoolbox-3/archive/Psychtoolbox-3.0.11.zip](https://github.com/Psychtoolbox-3/Psychtoolbox-3/archive/Psychtoolbox-3.0.11.zip)
  3. Extract the zipped Psychtoolbox-3.0.11 file into C:\MyToolboxes
  4. Change file name to ‘Psychtoolbox-3.0.11’

3. Downloading Psychtoolbox for R2015b 32-bit
  1. DownloadPsychtoolbox(‘C:\MyToolboxes\Psychtoolbox-3.0.11’,’Psychtoolbox-3.0.11’)

4. Restart Matlab after it finishes downloading
5. type - C:\MyToolboxes\Psychtoolbox-3.0.11\Psychtoolbox\SetupPsychtoolbox.m
6. 

> > SetupPsychtoolbox

7. Type ‘no’ when asked to delete paths
8. Shall I delete all those instances from MATLAB/OCTAVE path? Type ‘yes’
9. “\*\*\* Matlab’s Static Java classpath definition file modified. You will have to restart Matlab to enable use of the new Java components. \*\*\*” Press RETURN or ENTER to confirm you read and understood the above message. Hit ‘ENTER’
10. It will give you a message that says “Done with post-installation. Psychtoolbox is ready for use.”
