How Do I Install and Uninstall the GPIB Driver on

[mkan@phys.ualberta.ca]

I download driver from http://sine.ni.com/apps/utf8/niid_web_display.model_page?p_model_id=12759, then I try Sweep.vi. In the visa, I refresh and can't find N9310A. What do I need to do?

You can start by answering some of the questions. What is the make and model of the GPIB controller you are using? What is the driver software (for the controller!) that you finally installed.

An additional questions that also needs to be answered is have you been able to see the controller and the instrument in MAX. Until you can, trying to use LabVIEW is probably just a waste of time. You have to get the basics done first. You started this whole thread about uninstalling drivers and you have not explained what you have done or why.

Hi, 

After NI.4882. drive, I could not find "gpib-32.dll" in "c:\windows\system32".

But I can find "NI4882.dll" in that directory.

By the way my statement of GPIB looks for "gpib-32.dll" and make error "unable to load "gpib-32.dll".

NI4882.dll and gpib-32.dll are different ?

Does NI.488.2 driver only install NI4882.dll not gpib-32.dll?

Then how can I install gpib-32.dll?

Thanks

Seong

Seong,

This thread is pretty old, I would suggest making your own thread so that we can focus on your problem in particular.  I found gpib-32.dll in my SysWOW64 folder, but can you explain what you are doing when you run into this error (A screenshot would help a lot).

Telling us what OS, LabVIEW, and 488.2 driver versions you are using will also give more context to your issue.

Matt,

I tried to run my old program that ran successfully in my old window 7 32 bit PC.

My program has Vbib-32.vb and NIGLOBAL.vb and looking for "gpib-32.dll" because Vbib-32.vb has the statement such as 

"Declare function ibwrt32 Lib "gpib-32.dll" Alias "ibwrt"(....) as integer.

But "gpib-32.dll" is not installed into c:\windows\system32 when I install NI 488.2 driver.

Right now I use window 7 64 bit PC, NI-488.2 ver 14.0 and I do not have LABView.

I just use PCI-GPIB board and use that board with VS2008.

I attached screenshot.

Thank you.

Matt,

I also found gpib-32.dll in c:\window\syswow64.(I did not notice that before).

So I changed the statement  "Declare function ibwrt32 Lib "gpib-32.dll" Alias "ibwrt"(....) as integer into 

 "Declare function ibwrt32 Lib "c:\windows\syswow64\gpib-32.dll" Alias "ibwrt"(..) as integer.

But the error comes as "An attempt was made to load a program with incorrect format".

How can I use gpib-32.dll in the syswow64 folder in my program?

Thank you

Seong

Finally, I solved my problem to use "gpib-32.dll" located in c:\windows\syswow64 directory.

I just compiled the program in 32 bit mode by

my vb program>properties>compile>advanced compile option>target cpu>x86.

Now I can use old vbib-32.vb and NIGLOBAL.vb module.

Thanks for everybody who reply my questions.
