Thread: Difference between windows 6 and 6.1

Hi there

Please can someone help me. I have Windows 6 standard installed on my phone, and it works great.
But i got myself a TomTom navigation software and are trying to install it, but it is not working, If i start the installation nothing happens. (like nothing). A friend of mine also have the same software but different HTC phone. His OS is windows 6.1 The application works on his phone. So i thought maybe that is why it is not working on my phone. Is it possible to upgrade to 6.1 or not
