3.0.10 error Win7 Matlab R2013a - invalid MEX-File error for MatlabWindowsFilesR2007a\Screen.mexw64

1

Hi there,

 

I know this question has been asked many times here, but I can’t seem to fix this on my own.

 

I can’t get PsychToolbox working on my Windows 7 Machine with Matlab R2013a. When I run AssertOpenGL I get an invalid MEX-File error for MatlabWindowsFilesR2007a\Screen.mexw64.

 

I’m running the latest release of PsychToolbox (3.0.10 - Flavor: beta - Corresponds to SVN Revision 3833) in Windows 7 running Matlab R2013a.

 

I’ve also installed the supplied vcredist_x64.exe

 

I’ve copied all the errors and versions in detail below.

 

Some help would be greatly appreciated!

 

Thank you ;)

 

Steven.

A very simple test call to the Screen() MEX file failed in AssertOpenGL, indicating

that either Screen is totally dysfunctional, or you are trying to run your script on

a system without Psychtoolbox-3 properly installed - or not installed at all.

 

This script or function is designated to run only an Psychtoolbox based on OpenGL. Read "help  AssertOpenGL" for more info.

 

A first more diagnostic test would be to simply type Screen in your Matlab/Octave console and check what its output is.

 

The returned error message by Matlab/Octave was:

Last Error: Invalid MEX-file '\\...\PsychBasic\MatlabWindowsFilesR2007a\Screen.mexw64': The specified module could not be found. (MATLAB:invalidMEXFile)

    \\...\PsychOneliners\AssertOpenGL.m,99

 

Error using AssertOpenGL (line 174)

Problems detected in call to AssertOpenGL;

This is just a wild guess, but it might work better if it was installed locally and not on a network share. Can you try putting it on c:\toolbox just for testing purposes?
