Answer 1

You should invoke the python that is installed within your environment. That is

source myenv/bin/activate
python path/to/script.py

In Unix, you would add the following #!/usr/bin/env python at the top of your script and this would allow you to run it without specifying the python binary.

source myenv/bin/activate
path/to/script.py

Possibly that works in Windows in the same way or differently.
