I am having a Sony VAIO model which was running with Windows 7 since i bought it 2 years ago. Now as i wanted a change, i tried to install new Windows 8.1 Preview on the same. Well installation went fine without any problem, even installed all required softwares and drivers. But there are few problems appearing including the most annoying one which says "The btvstack could not be started".
I tried checking device manager if there is any problem with the driver, but everything seems to be fine. Then why is error message keeps appearing every now and then. Any idea what is the issue? Please let me know some fix to get rid of the same. Many thanks.
