IPOD Nano 'update drivers' so I itunes can see the device HELP NEEDED

I have spent hours and hours trying to get this working but it fails me and I am close to cracking up.

It appears I'm on windows 8.1 with a 64bit operating system, however when I check most apps and devices they seem to pull out 32bit drivers. (When I tried to install an old version of itunes based on 32bits it failed saying I need to use the 64bit version).

Please see below:

I am trying to update the drivers for the portable device the IPOD but I can't. I also tried under disk drives on the left above and that too failed. I have read forums and forums and navigated youtube but the 'fixes' which are based on newer generations and IPOD phone seems to work. I have installed and re-installed itunes rebooted my PC a 100 times and nothing. Itunes is not seeing the IPOD. It's actually driving me daft. The PC is seeing the IPOD but as read only - it tells me the dick is write protected. Is there a fix ? I would love to get this IPOD going again.
