NI USB-8451 no visa alias

I am unable to view or change the visa alias, as you can see from the attachments the visa reference seems incorrect, but when I put it on another system I get "USB0::0x3923::0x7166::019328A3::RAW" as a reference with the same device drivers. I have un-installed the drivers and installed again, but no change. I have installed NI-845x_1400.exe from NI but no change. Is there something I am missing?

 

Thanks

Hi 

 

Thanks, I had installed that driver already but tired again by un-installing it and re-installing, restarting and plugging the usb into the machine, but it is still the same, no change.

It might be something strange with the VISA alias already set can you see if you can clear and set the alias through the tools menu?

 

See the KB below for detailed description

Also can you give an alias in that tool?

Hi Jonas

 

thanks for the reply, I have had a look at the alias' but there is nothng there for the usb-8451 as you will see from the attachement. I thnk I have tried everything short of un-installing all of the NI products from my dev machine but all that time to do so migh not help.

It might be something wrong with your VISA driver.

 

Can you try to uninstall that and install this

Will there be any differences if you run MAX as Admin?
