USB Driver issues

In the user manual for the discovery board, it says that an installation wizard should appear when I connect the board to my computer for the first time, but that didn't happen.  I downloaded the driver from here:

When I went to try to run some of the example programs (I'm using Keil), I had errors of the wrong file names for the drivers.  So I went into the file (C:/Keil/ARM/STLink/) and the file that the debugger was looking for -  ST-LINKIII-KEIL.dll - wasn't there, but there was a file named - ST-LINKIII-KEIL_SWO.dll.  I renamed the second one to the one it was looking for to see if that would fix the problem, but now I am getting an error ''No ST-LINK detected.''  Any idea on what I'm doing wrong, or a way to make this work?  Thanks for the help!

Which Discovery board? They make half a dozen different ones.

You might want to check the ST-Link utilities, and make sure you have the right firmware/drivers. You'll also want to confirm the ST-Link is present/found in Device Manager. Some of the older boards need to use the Keil ''ST-Link (Deprecated Version)'' debugger rather than ''ST-Link Debugger''

I'm using the STM32F3 Discovery board.  I'm not sure if this is an older one, but thanks for the help!

I know the driver thing is a bit messy, I had my own battles with the VL and F4 Discovery boards not playing well together.
