86100B IVI-COM Driver on LabVIEW 6

[zep]

Hi, I'm trying to control a 86100B scope using its IVI-COM driver on LabVIEW 6 (downloaded from Agilent's site), but I keep getting the "Class not registered in Untitled1.vi" message. The instrument is running Win98, whereas the client computer is running Win2000. I've installed the driver on the instrument itself, along with all the other software required by it, but the problem remains. I've tried this driver with two Win2000 computers (one as client and the other as server) and I'm able to open a ActiveX session, which does not happen when I do it with the instrument itself. I also tried to launch the server on the instrument using the DLLHOST application, but I never see it on the tasks list (I'm not sure if I did this step correctly)

Does anyone have a clue to what is happening?

Thankx...

The problem for us is to support a driver that we do not build.

Do you have an error code?

Isn't it an error of registration?

Please reference the Using an IVI-COM driver in LabVIEW document:

https://knowledge.ni.com/KnowledgeArticleDetails?id=kA03q000000x2PfCAI&l=en-US

The document is written for LabVIEW 7.1 but the concepts should be similar to LabVIEW 6.0.

If you continue to experience troubles with the IVI-COM driver, I do see 2 non-certified drivers on the Instrument Driver Network (ni.com/idnet) for the 86100A.

The "Class not registered" error is usually generated when one or more ActiveX/COM object could not be created due registration problem.  For your case, both 86100B IVI-COM driver DLLs and VISA COM DLLs must be correctly installed and registered, because Agilent IVI-COM drivers all use VISA COM API instead of traditional VISA-C API.  I recommend to try re-install the IVI-COM driver and/or VISA library.  Also you must use NI-VISA 3.0+ or Agilent IO Libs M01.00+ for correctly using VISA COM interface.
