Ok, some progress has been made.
I have managed to update to v2.1.28.0
But get a strange error when trying to update to v2.1.36.0
See attached.
Edit: Another step closer... v2.1.36.0 installed, but get device error when plugging in transmitter.
I got the drivers here..

I think I may have solved the detection problem as well.
Because the USB transmitter for the WPCTVPRO does not fit into the USB port due to the shape of the Vaio, I am using an extension cable. I think that the cable would need to be a high speed one wouldn't it? Although, when I plug it into the USB 2.0 port it still is not detected, but have ordered a USB 3.0 cable and will test it.
