DAQ board no longer showing up in MAX, nor elsewhere.

[bmihura]

I can no longer see my DAQ board in MAX, nor LabVIEW 7.1. It's a PCI-6023E, which was working fine last week.

I tried reinstalling MAX through the Control Panel >> Add/Remove Programs, but it is not there. In "Add/Remove Programs", II click on "National Instruments Software", but that causes my computer to hang.

I tried downloading the latest NI-DAQ, but it thinks it has nothing to install. I explicitly use it to remove LabVIEW 7.1 support, then re-install it, but my DAQ board is still invisible.

How can I communicate with my DAQ board again?

This may not be your solution but, I had the same thing happen once .. it was very frustrating ... took me a better part of a couple of hours to figure it out .. but it was really very simply ... I had been moving somecards around in the computers and although the 6220 card looked like it was properly seated ... it was not ... I reseated it (pushed harder) ...and everything came back .... Try that out ..

If after re-seating your DAQ device you still have problems, please let us know.

I reseated the PCI-6023E, then even tried a different PCI slot-- still no luck.

When trying a different slot and rebooting, Windows did the "Found New Hardware" thing, but MAX can't see it. All MAX sees under "Devices and Interfaces" is an empty "NI-IMAQ" devices folder.

I have never had any "NI-IMAQ" devices.

Any other ideas on how to read data from this board?

HI,

try to install the board on another PC, when this works, try to clean up your PC!

(del NI folder and any entries in the reg)

I agree with timo.But just remove your Daq. device while formating PC,insatalling,uninstalling NI softwares.

Go to Add/Remove Programs, then select National Instruments Software and select "Change". This will bring up a list of all the National Instruments Software you have on your computer. Remove NI-DAQmx and Traditional NI-DAQ from the list, then shutdown the computer and remove the device. Boot the computer up and install the latest drivers (NI-DAQmx 8.0), then shutdown again and put the device back in.

I removed the DAQ device, and tried to uninstall NI software. The only thing that uninstalled was NIDAQ800, everything else from NI I try to uninstall hangs my machine.

I tried the NI-PCI 6023E on two other machines; it works fine.

I reinstalled NIDAQ800 and it still does not detect my board.

Of course I could reformat my hard drive, but am reluctant to do that since that would take me days to reinstall everything. And everything else other than NI software is working fine.

Is there some brute force way to uninstall NI software, since the Add/Remove Programs approach hangs my machine?

Hello Bmihura,

There is a utility called MSIBlast that can be used to remove software from your computer when the Add/Remove Programs does not work.  For future reference, it sounds like some portion of your National Instruments software has become corrupted during an installation. Also, if your device does not show up in MAX, it probably is a result of an incorrect driver installation, and not a problem with the MAX program.

The first thing you will want to do is remove the hardware from your computer.  Then, to get the MSIBlast utility, copy and paste the following in an Internet Explorer web browser window: ftp://ftp.ni.com/outgoing/ 

Find MSIBlast.exe and drag and drop it onto your desktop.  To run the utility, simply double-click on the executable.  In the dialog box, make sure you have 'Show NI Installers Only', and you should see a list of National Instruments software installed on your computer.  Go through the list and select the components that you wish to remove and click the 'Uninstall' button.

Once you have uninstalled all of the software that you could not uninstall through Add/Remove Programs, restart your computer and verify that everything was uninstalled through Add/Remove Programs.  At this point, if you chose to uninstall LabVIEW, that should be the first thing to reinstall.  Otherwise, go ahead and reinstall DAQmx 8.0.  I would recommend re-downloading it from our website here , just in case the installer became corrupted during the download process.  After the driver is installed, now is the time to power down your computer and physically install your hardware in a spare PCI slot.  When you restart your computer, Windows should recognize new hardware and you should allow the wizard to install the driver software automatically.

I hope this helps, and if you have any further questions you can either reply to this post or directly contact an Applications Engineer by calling 1-866-ASK-MYNI.

Fixed, at last! Halfway....

That MSIBlast.exe utility did better at uninstalling NI drivers than Windows' "Add/Remove Programs", as it wouldn't crash, but I could never get the NI-DAQ installer to work again even though I removed everything DAQ-related.

My last attempt before re-installing Windows itself was to uninstall ALL NI software through Windows' "Add/Remove Programs", and that worked.

The downside is that I can no longer use Windows' "Add/Remove Programs" after dealing with the pesky NI drivers; it hangs. But at least I have a working DAQ board until I have more time to do a complete Windows re-install.
