I know that in visual studio 2010 there wasn't 64 bit version. Is there 64 bit version for vs2012?
No, there isn't.
Probably for the same reasons stated for Visual Studio 2010 (no need for the additional address space, and because for this application it would bloat it, slow it down and will take much too long to port to such an architecture, not to mention - the 32bit version works on 64bit machines).
