InpOutx.64 driver is NOT open.

Hi

I have a problem to run my experiment using MATLAB. I will use MATLAB to present stimulus and send trigger to BrainVision. A few days ago, I had installed a parallel port (we had LPT3) and downloaded inpoutx64.dill, io64.mexw64 file. And then I put them on the Window32 file. And then, when I run the MATLAB, the error message “Inpoutx.64 driver is NOT open.” Was popped up on the command window. I think it seems that MATLAB cannot send the trigger to BrainVision because I cannot find any triggers in BV.

Please let me know how to do.

Thanks.

"then I put them on the Window32 file"

Could you expand on that?

I am concerned that that might hint that there is a 32 bit executable involved.

And then, when I run the MATLAB, the error message “Inpoutx.64 driver is NOT open.”

What triggers that message? That is not a message that would come from MATLAB itself.

When I deleted all 32 bit files in my computer, inpoutx64 driver is open.

Thank you so much!
