If you cannot get the serial number then you are not communicating with the tablet or are not running the test command at the correct time in the sequence (many of the rooters do this simply mistake, they just click without reading what they're suppose to do).
You have to run the test, when it tells you too and not before
and not after
. For example, if you click next and then try to get your serial number it's too late. So, make sure you are reading the instructions and not proceeding to the next step until asked to do so.
If you are sure you're running the test to get your serial number when told to do so and are not getting it to work. Then the PC is not communicating with the tablet. Make sure you have turned on USB debugging, check your cable, make sure you have the tablet powered on.
Lastly, re-read the PDF and make sure you're not skipping a step.
PS> I only use Windows 7 64bit so that's not an issue.
