ADI v1.2.1

Fixed

• ADI starts on a Windows machine that has never had a compiler on it. The installer put
  everything in place and then Windows refused to run any of it: "the code execution cannot
  proceed because libstdc++-6.dll was not found", over an offer to reinstall that could not
  help. The released binaries were linked against a GCC runtime library that is not part of
  Windows and that nothing installs; they now carry it inside them. Install this version over the
  broken one — an ADI that cannot start cannot update itself.
