Until Jim make a better one (if he hasn't already) here is a 64 bit version:
http://cap.connx.com/chess-engines/new- ... eko-7.0.7z

[Vladimir Medvedev]

Updated to version 7.1.
Main change is strength limit options. GreKo's rating can be modified in the interval 1800...2400 - however, not precisely tuned yet.
Minor changes in time management scheme.
