WoW Error during patch update

Ever since the latest patch, the Battle . net launcher will get an error everytime World of Warcraft tries to update. I restart the launcher and the problem still exists. I have to open task manager, end process on all battle . net associated programs, including WoW Voice Proxy which i think is the main problem, restart the battle . net launcher, and then it updates without problems. Just wanted to document the fix so hopefully it can get fixed in the future.
