How do i deploy application on the machine w/o .net framework

Question

Hello, I am new in .Net Development. I have made one small application and now want to install the same on my friend's computer where .net framwork is not installed. I made a setup up project but the setup fails saying .net required. I understand that i need the redistributable copy of .net framework i.e. dotnetfx.exe to get success. But I just want to know how do i bundle dotnetfx.exe with my setup project ? Also when i tried to get dotnetfx.exe from microsoft site i couldn't download it. Really feel stucked. Thanks for the help in advance. N Shah
