it's a kind of site viewer program and I made it the EXE file using py2exe

It works fine on my computer and some other computer don't have python interpreter(it's Windows 7).

But the same file also do not work on another computer(it's Windows xp)

why does it happen?

is there something difference about windows?

I want to distribute my application who don't have Python:(
