I downloaded a x86 windows pro version and installed in my system. The mistake which i did is my system supports x64 but by mistake took a msdn x86 version of Windows 8 pro.
Because of installing x86 os i am not able to install visual studio 2012 for windows phone. It throws an error stating that ur system is x86.
It would be of great help if u can give solutions for this.
You will have to uninstall the x86 Windows 8, and install the x64 version to fix that sort of error.
