Generating a Win32 for Windows XP SP3 with VS 2012

Hi,

I have a WPF 4.0, compiled with Framework 4.03 in VS 2012, that is working perfectly in my Windows 7 machine.

I tried to run this application in a Windows XP SP3 and I am receiving the message that the application isnot a Win32 Application. I have changed the Plataform Target to x86 and it is still not working.

What should I do to make my application run in a Windows XP machine.

Thanks in advance
