Getting error messages upon startup after installing Lab View 5.1.1.

[atanas_petkov]

I have recently purchased a DAQ system along with a computer, which uses a readout program written in Lab View. however, after installing Lab View 5.1.1 on this same system, I started getting some error messages and the readout program no longer works. Here are the error messages:

"The \SystemRoot\system32\drivers\nidmmk.dll device driver could not locate the entry point ?single PointWrite@mdsSimpleDIGPortPrimitive@@UAEXKKKAAJ@Z in driver Nidaq32K.sys"

as well as

"The ordinal 2011 could not be located in the dynamic link library nidaq32.dll. An error occurred while loading VT Digital buffer write.vi"

I would greatly appreciate any help I can get.

Hello,

Installing LabVIEW should not effect an installation of NI-DAQ. However, it seems to me that we may have installed a different version of NI-DAQ on top of the current version. This is very possible because the old LabVIEW CD�s contain NI-DAQ on them.

In this case, there is not an easy solution, we could try uninstalling and reinstalling combinations, but it will probably save the most time and effort to uninstall all National Instruments products and reinstall them. The best way to do so is from the ADD or REMOVE Programs utility from the Control Panel. Then we want to remove the following registry keys (BE SURE TO BACKUP YOUR REGISTRY!!)

HKEY_CURRENT_USER\Software\National Instruments <-- Delete the entire tree!
HKEY_LOCAL_MACHINE\Software\National Instruments <-- Delete the entire tree!
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\PCI\ or \ISA and delete registry entries containing any keys with 1093 in them.

Do not worry if any of these trees are not listed. If you have Administrative rights, and you still cannot delete these keys, that is also OK. Continue with the remainder of the process.

Make sure that you do not have any of your own VIs or other files saved in the "C:\VXIpnp", "C:\Program Files\National Instruments", or "C:\WINDOWS\nidaq" folders. If you do, copy them to a different location. If you are concerned about keeping old virtual channels and your SCXI setup intact, then backup the "C:\WINDOWS\niconfig.daq" file, too. Delete all folders and files mentioned above.

Note: If you have Windows NT/2000, replace "C:\Windows" with "C:\WINNT" in the paths listed above.

Once these steps are taken care of, we should have clean system. You probably want to reboot and then reinstall the software. You should install development environments first, and then install drivers.

Just let us know if this does not take care of the problem, or if you have any questions on how to complete a step of the process.

Best regards,

NOTE: Turning off virus scan programs greatly increases the speed of uninstalling and reinstalling.
