I just installed Psychtoolbox-3 and when I tried to open a window using the screen command I got the following error

Invalid MEX-file
'C:\toolbox\Psychtoolbox\PsychBasic\MatlabWindowsFilesR2007a\Screen.mexw32':
This application has failed to start because the application configuration
is incorrect. Reinstalling the application may fix this problem.

I don't really know what this means or how i would go about just reinstalling the screen application.
Any help would be greatly appreciated!

I have the same problem. Is it due to Matlab or Psychtoolbox?

I'm not really sure, I never had this kind of error when I used other Matlab add-ons, i thought maybe it was a problem with the download?

Kate & Lisa,

please just run UpdatePsychtoolbox again. I made some changes and the installation should abort with an error message pointing you to a download location on Microsoft's website. You need to install/update a file from there, and follow the given instructions. It's basically a Windows problem due to Microsofts dumb design of their runtime libraries.

Oh and Psychtoolbox has its own user forum which you should use instead of this forum. I only stumbled across your messages by accident, usually no one will notice if you post ptb related problems here. This is the URL:

<http://tech.groups.yahoo.com/group/psychtoolbox/>

Please report back on our forum if it worked out for you. So far i don't have feedback from users if the fix works.

best,
-mario
