[Elecraft] K3S USB driver problem

[RLVZ at aol.com]

My K3S with Elecraft USB cable going the radio to  computer worked great on 
my old Windows 7 64-bit computer.  Now I'm trying  to use the same radio 
and same USB cable with another Windows 7 64-bit computer  and cannot get it 
to work as I'm having problems getting the driver  installed.  Some related 
thoughts:
 
1) This Windows 7 64-bit computer cannot  auotmatically find a Driver for 
the USB cable.  I'm, quite sure my  old W.7 computer installed the driver 
automatically without  me downloading it manually.
 
2) Since the new computer cannot find the driver  automatically, from the 
Elecraft website, I downloaded the Driver file: "CDM  v2.12.24 WHQL 
Certified" and then unzipped it to the Documents folder.   (there are 8 files within 
that folder)
 
Using Device Manager, I try to install the new Driver, but  regardless 
where I place the zipped or unzipped "CDM v2.12.24 WHQL Certified"  driver file, 
Device Manager reports that it "cannot find the  driver".
 
Please advise what I'm doing wrong?  Such as, it  there on particular file 
I need to select manually?  Or perhaps  this CDM v2.12.24 driver file needs 
to be placed in a particular  folder?
 
Thanks & 73,
