Hi Kchitiz, I am also interested in this question. In my opinion, Fedot just built the project for 32bit host (no matter whether on 32bit or 64bit system), which runs on 64bit system without any problem unless you need to link it with 64bit libraries/executables. Earlier there was a thread in this conference that addressed this topic and the result was, I think, that 64bit Windows are not officially supported. There were some hints though.
