Error trying to update via VISA Driver Wizard

You should check the old pc to see what drivers the USB instruments used.

The silabs and xilinx would not show in MAX unless they use a virtual serial port or they are USBTMC. The agilent is certainly one of those. When you use the VISA wizard, you tell Windows to ignore the drivers that came from the vendor and that you will be creating your own low level driver. That is why you should delete the files that the wizard created. If you had created your own drivers on the original pc, that is a different story but you have not said that you did that. If you hadn't created the low level drivers, I don't understand why you would decide to create them now.

No, let's keep everything here.

You brought up a good point. It did work previously at old workstation without my having to go to the driver wizard. I did deleted those files, however it still brought me back to square one.

 

I thought that if device manager picked up the devices attached but doesn't recognize then if I were to go through the Driver Wizard and force it to recognize it, that would have worked. But instead, the inf files were created, I tried to install them but failed due to access denied error. Also, it didn't even generate a pnf file along with it. That route was a bust.

 

The fact is though, it eventually didn't see the devices on the old workstation either. That is the troubling part. Now it isn't seeing on the new one either. I will go back to the old one and see if I can salvage the old drivers there and see where they are at the least. Its a start.

 

I appreciate your help. If you can think of something else or anything at all that would be most helpful. Thank you.
