New submission from Piyush Patel <piyush.428ec at gmail.com>:

I am facing a very strange issue.
I am working on a C++ application which embeds a python.
As per documentation i have the dependencies added from python (/libs and /include directories) to C++ application.
I am using Py_RunString() to run simple python code.

Python code is simple:

import os
def Func():
    return 10.0

The application run smoothly when i have python installation in directory like 

but if python installation is in directory like "C:\MyPython\" or default installation path AppData\local\program\python\pythonxy\ , python code errors out.

the error i am getting is "__import__ not found".

I have used PyErr_Fetch to retrieve error.

It's really strange that the python installation directory affects how Python  code is run.

It seems it have a problem running "import os" statement or any "import" statement.

Could you help me how i can resolve this issue?
