have a read of this, sounds like the same problem on win 8
post #4 might be your answer
"Have you disabled digital driver signature? For flashtool you need MTK6589 USB VCOM drivers!
Open device manager, open flashtool, plug in your phone and install driver manually with open flashtool!
First you have MT65xx Preloader in device manager for two seconds when you plug, double click and install driver manually.
Then you should have MediaTek PreLoader USB VCOM Port! Now it should be installed correctly."
here are the VCOM drivers from the site
