I had the same problem too. I'm using Windows 10 with the anniversary update.
(I'm not sure its use of a global hook stored in an EXE is safe anyway. I think you have to have these things in DLLs, because the hook runs in each process's context, so each process needs its own copy of the code. Obviously it must work for at least some people though... I wonder how? Will have to try building it when I get a moment.)
It's very possible this isn't quite the same as the original, which I've still yet to actually experience - however you do get a click each time you press and release a key, so it's presumably not a million miles off.
