Instrument I/O Assistant not installed correctly

[RxTx]

I've been troubleshooting this problem for over 2 weeks now and every response to this question that has found success I have tried, but was unable to fix the problem.

in labView, double selecting the I/O Assistant it reads the infamous text

"I I/O Assistant Not installed correctly or..."

I have downloaded the latest NI-VISA 5.1.3 (or the latest), NI-488.2.  In order to install the NI-VISA I needed to find a .net 4.0 framework & Visual Studios 2003 or better.  After this failed, I downloaded the DCD_AUG12_1 & 2_Downloaders.  After that did not work it left me considering if my machine or equipment is the problem, or if the software is just unable to support these features.

My System Information includes

Windows XP 32 bit

Drivers Include:

8757d

Agilent 34401

HP8753x

Connection Attempting:

GPIB Ethernet

When launching labView I receive an error

"The web server cannot start.  Is the webserver port already in use...

...labView Network Address is in use"

When trying to communicate with the machine connected to my computer, I can write to it, however I cannot read from or query information from it.  NI says its connected just fine.

Lastly my NI is 2005 and Labview is 8.0

I am pretty novice in this equipment and technology.  So if there is any specific details that I need to add, please let me know and I will update the post to include such details.

Anyone have any suggestions?

Hello RxTx,

You have to manually select to install the I/O assistant when you install your VISA driver. You did not mention if you were doing this or not so I suggest giving that a try. This KnowledgeBase article has details on that:

I was installing the I/O Assistant while installing the VISA driver.

Thanks though

RxTx,

It looks like you might actually have too new of a version of VISA. Please see the following KnowlegdeBase article for more information about which version you require:

It looks like VISA 4.3 is the newest version you can have for your version of LabVIEW. 

Let me know if that fixes the issue!

Thanks,

Thanks, that did get the I I/O Assistant to start working.  I dont suppose you know of any drivers that are acceptable with the 8569B Spectrum Analyzer?  I cant seem to find one specifically for this equipment, and im getting syntax errors.  The closest I found was 8566C (or B).

According to this link, it looks like Agilent no longer supports the 8569B. I would get in touch with them if you're looking for drivers.
