VISA Interactive Control will not load

[prone]

I have a problem connecting to my GPIB card using labview (in that it won't connect) and it seems to be related to the fact that the VISA Interactive Control will not load.

I try to run VISA interactive Control and initially the splash screen appears. It then says that it is finding VISA resources at which point it crashes and gives a standard windows Xp error message. The message is that  VISA Interactive Control has performed an illegal act and must be closed.

I have uninstalled and reinstalled the VISA components several times with the same problem reoccuring has anyone got any advice?

I am using version 4.3 of VISA.

Dear prone

Many thanks for your forum post. Do you have Measurement & Automation Explorer (MAX) with your LabVIEW software. If so does your NI-VISA devices appear within MAX? What kind of GPIB connection are you doing? Is it a GPIB-USB connection and therefore you will need the NI 488.2 Driver too. Please update your driver to the latest version of VISA:

Version 4.6 of NI-VISA Driver can now be downloaded from the following link:

Please also see the forum post I have added in below; as your NI-VISA may be needed to be configured to be the primary VISA.

Please let me know how you get on as it does sound like a corrupt install of the VISA files. Thanks!

       Thank you for your reply. I have got MAXand no VISA devices appear there, however the GPIB card we are using is not from NI and as I understand it will not appear in MAX anyway?

I saw your previous  post before and checked what you suggested. The NI-VISA was set as the primary VISA.

I will give the updated version of the VISA driver a go and see what happens.

Hi prone

Thanks for the quick reply. If the GPIB card is a third party non NI card then no it will not show up in MAX. Let me know how you get on with the installation of the drivers and we can take it from there. Cheers
