Question

Hi all,
Just bought a Sony 4gb walkman NWZ-S616
Installs ok on Sony VAIO laptop computer, but will not install to desktop PC.

An information bubble appears saying;

Found New Hardware
MTP Device

That's all that happens.

The device manager says Device could not start (Code10)

Windows XP SP2
WM Player 11
