Hi

The PRO-668 is not supported by Scancat, I wish it was.
 Nor does any other software company to my knowledge.
  This is the same as a GRE-PSR-800 or Whistler WS-1080 Whistler.
   RS/Whistler says their software is "Proprietary"

Here are several links that explain the "problem" with our not being able to support these radios

    http://www.scancat.com/f-a-q/supportedscanners.html

    http://www.scancat.com/pro668

    http://www.scancat.com/whistler



As to more current drivers for what we DO support by Radio Shack:
 
This link is to the drivers we have on our website
      www.scancat.com/drivers

This is the latest one I know of for Radioshacks
http://scancat.com/drivers/20-546_RS_Win7-8-10_CDMv2.-2-10W-HQL-Certified.exe

But we don't make or sell RS cables, we only provide a "copy" of drivers we know of

 if these do not work you need to contact Radioshack tech support
