Ni488 2.2 Uninstall

[Ed M]

I have recieved the Missing or Damaged GPIB-32.dll error message and was trying to follow the directions to fix. Uninstall then reinstall. The Drivers do not appear in my Add or Remove Programs window preventing me from uninstalling. I am using windowsxp  and a KUSB 488A usb to gpib. any solutions would be a great help.

The KUSB GPIB controller is made by Keithley - not NI so I'm not sure why you posted here. Try www.keithley.com.

yes it is made by keithley but the drivers which i wish to uninstall are NI software. Specifically NI488 2.2. The goal is to use labview to drive a Keithley 2400 source meter. The OEM drives provided by the product do not work with labview, which is why I tried the NI drivers. As I mentioned one of the components did not install and I need to uninstall the NI drivers to fix the problem but can not. If there is a software message board for the NI drivers for a GPIB USB device that would be helpful to know and I will redirect my question otherwise Keithley does not have solutions for NI software issues.

Ed,

The correct driver for the KUSB-488A is supplied with your device, you should be using it and not NI-488.2 which often is installed when you install LabVIEW.

Most likely what happened in your case was that you installed the KUSB (CEC) driver and then installed LabVIEW or some such NI product and drivers which included NI-488.2

For the KUSB-488A to work properly you must first remove any installed GPIB drivers (e.g. NI-488.2), then install the driver supplied with your device or download the newest version from the Keithley website (now called GPIB-488 version 9.0) and you must reboot your system.

note -- If you do upgrade to version 9.0 driver make sure your "NI-VISA Passport for GPIB" is turned on and the older "KEVICEC Passport Library for GPIB Instrument" is turned off, if it is present. If you still have problems or questions about the driver, I would contact Keithley for support.

Good luck.

One further note...the KUSN drivers do support LabVIEW and supply their own GPIB functions.

You can also talk in LabVIEW using NI-VISA.

Thank you for the reply but you failed to answer my question. How can I uninstall the NI Drivers so that I can install different drivers? Is there a special name they are under in the Add Remove programs window. No NI programs appear in mine. Is there an uninstall feature somewhere in the download that I can use? Once the NI drivers are gone I know what to do but I need to UNINSTALL NI488 first. Again I dont have an uninstall ability from the Add Remove Programs window.

You did not originally mention that you tried to install NI drivers for a Keithley device.

Go to add/remove programs and open National Instruments Software. If that is not listed, I don't think you installed any NI software - including LabVIEW.

Ed,

Open up your Control Panel Add or Remove Programs, and look for the entry "National Instruments Software".

Click the change/remove button and you should see NI-488.2. Select remove and then reboot.

You can now install the KUSB driver.
