Ok, I have the correct version. I can run "from visa import *" and get
no error. How ever when I run this command I get and error:
My_Instrument = instrument("GPIB::5")
Traceback (most recent call last):

My instrument is on GPIB 5 and I can do a *IDN? with another program
and get a response. So I must still have something not configured
correct. Getting closer though :)
