py2exe deal with python command line inside a program

[im_smiling]

Thanks for taking time to help me. If I use either way, requiring
python being installed, or allow source codes exposure, it seems in
some degree, there's not necessarily to make the executable package
any more, which is very frustrating....

Suppose I take the first way, python environment must be on a machine,
how can I have py2exe find a specific file path, for instance as
below, 2 up levels from running director,  how to find myscript.py in
py2exe? Since in customers' machines, C:\dev\mysricpt.py doesn't
exist....

python environment: running directory - C:\dev\level1\level2\test.py,
suprocess directory-C:\dev\mysricpt.py
py2exe C:\dev\level1\level2\dist
