OK. I downloaded the new wallet. Now what? (facepalm incoming)

This wallet fixes a bug in PoS code - you should now begin to stake properly (perhaps after block 59860). The next update (in several hours) will contain the PoSA code.
Unless I missed something obvious (probably did) I haven't found a way to start the new wallet. Is there a startup exe in one of the folders?
The source was uploaded by accident, the link has been fixed with a working .exe file.
