PXIe 8431/8 on win 7

[miklore]

Dear members,

I would greatly appreciate if somebody helps me out the issue im faceing.

We bought NI PXIe 8431/8 Serial device and I tried to install its driver on win 7 after setting the hardware properly (put the pxi 8431 on 2nd slot).

Everything passed ok when i installed s/w provided by NI and after finishing it asked me to restart computer and i did.

Computer finds PXIe 8431/4 exactly by its name. Hoverwer the problem is it has 8 ports, nothing appeared.

I mean I had to able to have 8 port to open but no ports available.

And I did this steps on Win XP and everuthing is OK. I can open 8 ports and write/read.

Could you pls tell me what is problem with Win 7? On the disk of the PXIe 8431/8 there is written that win 7 supported.

No idea what to do... I cannot downgrade my OS cuz its licenced.

Thanks a lot.

I assume you are running NI-Serial 3.5.1 this version Does have support for Win7.  Support for PXIe devices was not added until version 3.6. available here
