IVI Connection Issue

I'm trying to connect to an Agilent MSO-X 4154A scope with the IVI driver.  This is my first time dealing with IVI drivers although I have experience with standard VISA drivers.  I have the IVI Compliance Package 4.6 installed and is displayed in the software tab of MAX.  I installed the IVI driver for the scope from idnet.  The scope is connected over ethernet.  I can see the scope in MAX under the "devices and interfaces" tab and tested communication to it by sending the *IDN message.  That was successful.  In the IVI tab I created a new driver session for the scope and logical name.  I believe I have that setup right.  

 

In Labview 2013 I loaded the example "IviScope - Acq Dual Wfm Edge Triggered.vi."  The first problem I encountered was that when the VI is loading it can't find "IVIscope.dll."  If I browse for it I can find it in the "C:\Program Files (x86)\IVI Foundation\IVI\Bin" folder.  The VI seems to load ok if I tell it to choose the dll in that folder, but I still question why it doesn't find it in the first place. 

 

The second problem is that I don't see the logical name I created in the dropdown menu of the example VI.  It doesn't show any logical names even though the logical name I created is clearly shown in MAX.  I'm not sure what the problem is.  My first though was that the IVI compliance package was bad but I tried a reinstall of that and it didn't help.

 

My system is:

Windows 7 64bit

IVI Compliance Package 4.6

Labview 2013

VISA 5.4

 

Any help would be appreciated

Have you also installed the IVI-C specific driver for Agilent instrument?

You should first make sure you can run the specific driver. To do that you don't need to configure anything under the IVI Drivers section in MAX, just use the VISA resouce name in the Initialize VI.
