Hello, im trying to install psychotoolbox on on windows 10 with matlab 2016a. I followed the instruction, but in the end it is showing me: “Error in DownloadPsychtoolbox (line 707) svndownload(targetRevision, dflavor, p, downloadmethod);” Going to line 707 it is showing: “% Download via Subversion: svndownload(targetRevision, dflavor, p, downloadmethod);” Does anyone know how to fix the problem? Greetings, Jasper ---

Hello dcnieho, thanks for your answer. This should be the complete error message: > > DownloadPsychtoolbox(‘C:\toolbox’) > > DownloadPsychtoolbox(‘C:\toolbox’,‘beta’,‘’, 0) > > Requested flavor is: beta > > Requested location for the Psychtoolbox folder is inside: C:\toolbox > > Using optimal client for subversion checkout. Good. Your privileges suffice for the requested installation into folder C:\toolbox. I will now download the latest Psychtoolbox for Windows. Requested flavor is: beta Target folder for installation: C:\toolbox Downloading via Matlabs integrated SVNKit: This can take multiple minutes. There may be no output to this window to indicate progress until the download is complete.

The error is “org.tmatesoft.svn.core.SVNException: svn: E175002: connection refused by the server” try on a different connection if you can, or try to restart the computer/matlab. If none of that works, you may try the offline installation method. You lose in-place updates that way, but have a working PTB install 🙂 Cheers, Dee ---

Thanks a lot. That was already very helpful! I´m now trying to do the offline installation, scince it is very difficult to get acces to the server from my university. I followed the “setup Psychtoolbox” instructions ( [Psychtoolbox-3 - SetupPsychtoolbox](http://psychtoolbox.org/docs/SetupPsychtoolbox) ) , but in step 3 trying to set up the psychtoolbox it is saying: > > SetupPsychtoolbox (‘C:\toolbox’) > > Undefined function or variable ‘SetupPsychtoolbox’. Do you know what to do here? Thanks a lot ! ---

Thats not what the instructions say. If you unpacked PTB into C:\toolbox (check that SetupPsychtoolbox.m is directly in that folder), then in matlab, execute: cd(‘c:\toolbox’) SetupPsychtoolbox
