M P G H had chams Dl's but the latest one got patched. as for the title, win7 is backward compatible with vista so all vista injevtors should work. I recommend PerX or Valkrie injectors. Also if it still wonr inject properly, right click on the injector and select properties. Then goto the compatibility tab and change it to watever OS you think i will work with..(vista SP2 or XP SP3 are the best)
