Windows needs to be restarted so necessary changes to system files can be made before continuing.
For these items, make the following changes: Uninstall these programs. Open Control Panel and search for "uninstall a program". CxVCap, Video Capture Driver
while trying to upgrade windows7 with new version. i saw on net that some people have the same problem, but no solution.
well the problem was in my tv card (or it can be with some other capture device).
i solved it by manually deleting sys files from system32/drivers that are related to my tv card. in my case it was cxavsvid.sys (with mouse over you can see file description) and after that it worked!
it seems so simple but after hours and hours searching for solution and trying everything, uninstalling drivers, apps, cleaning drivers, finnally i tried this and it worked.
