Hello everyone! I am new to MatLab and psychtoolbox and am attempting to download psychtoolbox onto an old 32-bit Windows 7 computer. Here is what I have done so far. I would greatly appreciate any insight or help into solving this problem. 1. Create path ‘C:\MyToolboxes\’ in file explorer 2. Getting a hold of the correct Psychtoolbox file for R2015b 32-bit - went to → ([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)) and got the file below - 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) - Extract the zipped Psychtoolbox-3.0.11 file into C:\MyToolboxes - Change file name to ‘Psychtoolbox-3.0.11’ 3. I then punched in the following code: > > DownloadPsychtoolbox(‘C:\MyToolboxes\Psychtoolbox-3.0.11’,‘Psychtoolbox-3.0.11’,‘Psychtoolbox-3.0.11’,0,1) "Target revision: Psychtoolbox-3.0.11 Hmm, requested flavor is the unusual flavor: Psychtoolbox-3.0.11 Either you request something exotic, or you made a typo? We will see. If you get an error, this might be the first thing to check. Press any key to continue… DownloadPsychtoolbox(‘C:\MyToolboxes\Psychtoolbox-3.0.11’,‘Psychtoolbox-3.0.11’,‘Psychtoolbox-3.0.11’, 0, 1) Requested flavor is: Psychtoolbox-3.0.11 Requested location for the Psychtoolbox folder is inside: C:\MyToolboxes\Psychtoolbox-3.0.11 Using optimal client for subversion checkout. Good. Your privileges suffice for the requested installation into folder C:\MyToolboxes\Psychtoolbox-3.0.11. Hmm. You already have an old Psychtoolbox folder: C:\MyToolboxes\Psychtoolbox-3.0.11\Psychtoolbox That old Psychtoolbox should be removed before we install a new one. First we remove all references to “Psychtoolbox” from the MATLAB / OCTAVE path. Success. Now we delete “Psychtoolbox” itself. Success. Your old Psychtoolbox appears in the MATLAB / OCTAVE path: Your old Psychtoolbox appears 997 times in the MATLAB / OCTAVE path. You didn’t say “yes”, so I’m taking it as no. Success. I will now download the latest Psychtoolbox for Windows. Requested flavor is: Psychtoolbox-3.0.11 Target folder for installation: C:\MyToolboxes\Psychtoolbox-3.0.11 **Error using DownloadPsychtoolbox\>svndownload (line 815)** **Invalid ‘targetRevision’ parameter ‘Psychtoolbox-3.0.11’ specified. Not a valid** **revision spec!** **Error in DownloadPsychtoolbox (line 736)** **svndownload(targetRevision, dflavor, p, downloadmethod);**" I messed around a bunch trying to figure out different combinations but none were successful. Let me know if you guys have encountered this problem in the past. ---

you shouldn’t run downloadpsychtoolbox, but setuppsychtoolbox in the folder that you unzipped ---

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.

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.” ---

All you needed was steps 1 and 3, with the DownloadPsychtoolbox file from our website. Everything else was just you creating busywork for yourself. Or 1, 2 and 6 if you decided to download the zip file instead, for a download that is much larger. -mario
