how to remove a duplicate driver?

[Jonas_Stein]

i have a Leybold 23xxxx pressure meter. By accident there are two Leybold 23xxxx drivers in the system now and i get strange errors with my VIs.

I have installed one driver via LV (this is a very old version)

and there is another (newer)  Version i dont know where it came from and why NI did not install the latest version.

How can i remove the unused drivers?

There is a old unused 2009 LV version still installed, but i could not find a uninstaller. Will i have to remove it with some tricks, or can it stay?

Instrument drivers are normally placed in the instr.lib folder and are nothing more than folders that you can delete. You either manually downloaded the zip file or used the Tools>Find Instrument Drivers wizard. The exception is IVI drivers. These do have an uninstaller.

Instrument drivers are in the "LabVIEW\instr.lib" folder. Each driver should be in its own folder. To delete it, just delete the folder. You may need to update the palette menu to reflect the removal of the directory.

Also, what do you mean by NI installing the driver? Are you referring to using the Help -> Find Instrument Driver? If so, what did you enter in the search criteria? Leybold isn't even in the list of manufacturers.

i entered Oerlikon (i think Oerlikon is the new name) the Gui can only install. And removal has to be done manually on console or filemanager, right?

Hi,

you can find the driver in:

C:\Program Files\National Instruments\LabVIEW x.x\instr.lib

x.x stands for the LabVIEW version

there you can delete it!

Best regards

after deleting the bare driver files in lv2009 and lv2011 and all other directories i copied one working driver into the lv2011 intrument dir and it works now.

Thank you all for your help.
