Windows 7 with labview 8.5 and NI-8451

[miso2562]

Hello,

I am using LabVIEW 8.5 with NI-8451 device on Windows 7. I installed 1.1 driver for NI-8451, but I am unnable to access any subVI connected with NI-8451.  Can you advise?

Thank you.

Hi miso2562,

The issue is most likely compatibility between the drivers, LabVIEW, and the OS. LabVIEW 8.5 is not supported on Windows 7 (only up to Vista), and NI-845X 1.1 is not supported on Windows 7 either (only up to XP). Also, NI-845X 1.1 does not support LabVIEW 8.5 either (only up to 8.2).

Ideally, if you use Windows 7 you should have LabVIEW 2009 SP1 or newer and NI-845X 2.1 or newer (1.1.4 could work as well). If you can move to XP, LabVIEW 8.5 and NI-845X 1.1.1 should work.

As for your main question "unable to access any subVI connected with NI-8451", do you mean they do not show on the function pallete?

Hello,

thanks for your reply. Yes, when I try to access subVIs on functions palette under Instrument I/O - here not even the NI-8451 device is not visible. I also tried the 2.1 driver for NI-8451, but that on the other hand does not support Labview 8.5

I was working with this configuration on Windows XP and everything was OK but I had to switch to Windows 7.
