Please use 64-bit Python and 64-bit compatible pywinauto: download from github or find any other 64-bit compatible pywinauto modification. Just note my version requires pyWin32 extensions which is in ActivePython distributive by default. BTW, you will get more detailed log for RemoteMemoryBlock failures - there are few improvements in this class too.
