simple parallel port question

[Marco >.<]

Dear everyone,
I want to control some pins of the parallel port to be high voltage. So I read this NI webpage
http://zone.ni.com/devzone/conceptd.nsf/webmain/72C6FC6CE4AD4D1386256B1800794596?opendocument&node=DZ52058_US
I follow the instruction to connect pin 11 & 12 to ground and checked my LPT1 address is 378, but error message comes out when I run the program. Could you please help me to solve the problem

thanks

It seems you are running windows XP.
The old inPort and outPort VIs are not supported under Windows NT/2000/XP.

You should upgrade to LabVIEW 7 (or higher) or follow the instructions HERE to install the accessHW utilities.
