Preliminary judge for ARX2012 platform set the default compiler v90, if you only have a vs2010 installed or not installed vs2008sp1 vs2008sp1 compilers, as well as the corresponding Windows MFC SDK, it might be such a problem, set the platform instead vs2010 own platform set v100, can be resolved.
My platform is a complete set, never had this problem before. One problem encountered by users, posted after the way I resolve to avoid such problems and there are people there.
