I am not sure if you are the same person in support email, but it's likely a fault with Norton Anti Virus as per the FAQ you have to disable Norton Life Lock. The part of the message regarding mission builder is generic, ignore that bit it is just a suggestion. The first bit is the actual error.
Basically, WOFF is trying to simply copy a file, and it's locked or blocked. If you have not contacted support then try the above and then contact support if still a problem.
