I'm new to python. I've installed both Python 3.2.2 for x64 and Python 2.7 for x86 on my 64-bit windows machine. I've got some python code that are coded for python 2.x versions. But every time I try to run them by double clicking it is interpreted by python 3.x.

How do I force them to use python version 2.7, may be using some directives or using a BATCH script?
