双击win7无法导入声音文件吗？

Question

I make a code test.py like this:

import soundfile
print("import success")

when I try to run this on windows 7， I can only run successfully by cmd：

python test.py

but I cannot run it by double click on test.py, it's too fast to dispear, I can see it display:

no module named soundfile

And I notice that, when I double click test.py on windows 10, it successed.

THX to @BoarGules, by using

where python

in cmd. I replace python path from python2.7 to python3 in regedit HKEY_CLASSES_ROOT\\Python.File\\shell\\open\\command . Then double-click working!
