That's why I wrote that you could just rename the folder. In that case if it didn't work you could just rename the setting folder back to the original name and nothing would have changed.
As for the Origin download, try making sure Origin is updated. Also, try starting Origin as administrator. What update is it trying to apply? A BF4 update? An Origin update? Or something else?
About the keyboard problem, does it still happen if you disconnect your keyboard?
My Origin is always up to date. I have no idea what it's trying to update, knowing EA, could be a screwup. download
