problems finding serial port

[Dand]

Having used LabView for some years in my last job, I am trying to get it used in my new one.
I have downloaded the evaluation software to prove to my boss it is worth having.
However, the simplest task is proving difficult.
I am communicating over serial with an instrument and cant find any ports.
I have used the visa search facility set to ?* (find all) it returns an error -1073807202 immediately.
Is the evaluation software capable of using VISA?
If so why can I not use any visa items without this error occuring?
Cheers

VISA is a seperate installation to LabVIEW (Like DAQ drivers). Make sure you have VISA installed on the computer you are working on.

Good luck

Dan,

Shane's correct. Check out this KB:

It has links for VISA. If you already have VISA installed, it's probably an older version, or was installed before LabVIEW, or is corrupt.
