usbser.sys USB Driver for Arduino Due

I have setup 3 PCs that have worked with the USB port to Arduino Due. I was setting up a PC #4 and the driver was not present. Win 7 64-bit. What files do I need to copy copy?

The PCs that are working indicate that C:\Windows\system32\DRIVERS\usbser.sys is the only file that is logged as a driver. I copied that over into the PC#4, and tried to use it to 'update the driver':not successful.

Any actionable suggestions are appreciated. Thank you

Update: I found the driver per these instructions:

My drivers were installed in: C:\MATLAB\SupportPackages\R2015a\arduino-1.5.6-r2\drivers

If you want to create the setup of USB port with fixing usbser.sys file the you have to need the copied the file and update the driver.
