As title, but after installing it, I found out that I do not have the mex file for it, so I still get the following message:

--

This mex file seems to be missing or inaccessible on your Matlab path or it is dysfunctional:

&nbsp; Eyelink.mexw64

--

Is there any simple way (like rename the&nbsp;Eyelink.mexw32 file) that I can use to fix this problem?

If anyone who can help me need the new toolkit, feel free to contact me through email:
