Visa Error -1073807195 in GPIB Control

[WenyanJiang]

I copied a labview program developed in LabView 2009 Win XP to my new operation system Win 7 with LabView 2013. I got the Old Visa Open error as titled when I run it for controlling Agilent 4149A. The program works fine in LabView 2009 (Win XP) using same set of hardware. Would this be a compartibility problem? I'm using Agilent GPIB/USB interface. 

Thanks.

When using an agilent adapter search for agilent and gpib
You have to enable another passport for this.
As far as I know you can do that in the measurement and automation explorer ( max)

I already enable the  NI VisaTulip.dll, if that's what you meant.
