WINIO.SYS and Parallel Port on Windows 7 (64 bit)

Hello

I have several laboratory software programs that use a parallel port to access equipment. We just got a new Windows 7 (64-bit) computer and I am trying to move all of our equipment to this machine. We are using MATLAB 2009b.

When I run the matlab scripts, I use the following code:

        obj = digitalio ('parallel', config.lpt_port);

and get the following error:

??? Error using ==> digitalio.digitalio at 115 PARALLEL: Could not start the WINIO.SYS device driver.

When I open up the Device Manager and look for non-plug and play drivers, winio.sys does not show up. I am an administrator on the computer running Matlab from an admin account.

How can I fix this?

Thank you in advance for your support.
