Problems uploading to Aruino board

When i try to upload a simple blink sketch to my arduino Uno ,I get this error

The Program can't start because libusb0.dll is missing from your computer. Try reinstalling the program to fix this problem

I visited the libusb website I looked at the downloads,

Where do i place the downloaded file???

What do i do

I had that message over a week ago and all I did was re-install the whole package which worked here.

On my computer it is located in multiple locations but here are my Arduino ones.
You may want to use your C drive as my system is a split install.

D:\Program Files (x86)\Arduino (I store my programs on my D drive)
D:\Program Files (x86)\Arduino\drivers\ia64
D:\Users\Username.arduino-create\avrdude\6.3.0-arduino2\lib (I store Users on my D drive)

Two of my GPS also use this lib so you may find other instances
