ive been having the same problem, so i installed my mp4 playe ron another pc and it worked, and in doing so i realised what i had been doing wrong...
when installed your mp3/mp4 player...
1. wen the first sintallation screen comes up, click '3. no not this time'
2. then select 'install from a specific location'
3. select 'dont search i will find the driver myself'
4. then you should see a list of devices, select ''USB 2.0 (HS) ADFU Device' then click next
it should install, when the error comes up just click 'continue anyway'
after that the upgrade tool finally detected my player, but so far i hav'nt been able to find a compatible firmware
