I got rid of all the drivers I had installed for cleanflight, got rid of zadig. Anything and everything to enable myself to start from fresh on the whole process. So now have reinstalled the drivers but it won't install Zadig. I am, as you mentioned earlier,pretty sure its this computer. But its all I have and i managed to get on cleanflight on the same machine with my naze boards. Problem I have at the minute is my very limited computer knowledge. The virtual com port on device manager has a yellow triangle in front of it. Windows asks if I want to update driver to make it work. I tried and it went on an endless search of the internet, so i ended that. All I need to do is get that Com port working and I think I will be in.
