Answer 1

you should reduce the target framework of your Project. VS2012 runs with .NET 4.5 as default, Windows XP does not support anything higher than .NET 4.0.

You can go to your Project Properties and select at the tab Application the Target framework.

Answer 2

Try the workaround mentioned in the following link.

But still you need to open up to us to give accurate solution.

Answer 3

Make sure you have installed .Net framework in target machine. Windows XP does not support .NET 4.0 and higher

Answer 4

Additional to this, just make sure the platform target of the program is not x64 if you are running it in a 32 bit machine. .Net framework 4 should work in windows XP machine.
