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):
  File "C:/Users/Rivetmr/MyPythonScripts/My_GPIB.py", line 2, in
<module>
    my_instrument = instrument("GPIB::5")
  File "C:\Python27_32bit\lib\site-packages\pyvisa\visa.py", line 288,
in instrument
    vpp43.parse_resource(resource_manager.session, resource_name)
  File "C:\Python27_32bit\lib\site-packages\pyvisa\vpp43.py", line

    byref(interface_board_number))

    raise visa_exceptions.VisaIOError, status
VisaIOError: VI_ERROR_INTF_NUM_NCONFIG: The interface type is valid
but the specified interface number is not configured.

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 :)
