NI USB-8473 Windows can not find Driver

[bkl]

After I install my CAN Software 2.6.1 and connect my USB device, Windows starts the Hardware Wizard but, can not find the Drivers for this device.  I started out with 2.4 and uninstalled and reinstalled it which did not help and then I upgraded to 2.6.1.  This did not seem to help either.  My impression is that this is something to do with Windows or the computer, but I thought I would ask if anyone has seen this problem before in case it is a hardware or software issue.

Hi,

Thank you for your post.  The NI-CAN driver is an inf file titled nican.inf.  Instead of automatically detected the driver in the Found New Hardware Wizard, try browsing to the nican.inf file.  This file is found in the following directory: C:\Program Files\National Instruments\NI-CAN\staging.

If this doesn't work, I would run the Microsoft Windows cleanup utility linked below and remove all NI-CAN registries from your system and then reinstall the driver once again.

I'm trying to install the Can2.7.4 driver on my PC, then it always tells the driver is not properly installed. An error occurred during the installation of the device. Access is denied.And under the system hardware, this driver is marked by ! yellow. So this driver doesn't work.

Microsoft windows clean up utility is removed from the web-site that u provide!

Hi,

Thanks for this tip, this was the answer to our problem. One small difference that may be worth noting , the .inf file one my PC was located in the C:\Program Files (x86)\National Instruments\NI-CAN\staging

directory. once winows installation wizard was steered to that file everything went as it should.

Thanks again.
