    Easiest fix is to do the same as we did in 3.14, and stop trying to be clever about the default value. Though I'm still not even totally clear on how we're getting the wrong one - I guess Wix is messing up search path order or something.

    Fixed now, and we are planning to release the next 3.13 update next week.
