title: How to solve "Error: [Win Error2] The system cannot find the file specified"
body: <p>I want to set up a python3 virtual environment in my Workspace. I have two versions of python, installed in the following paths: <code>C:\Python\Python27\python2.exe</code> <code>C:\Python\Python38\python3.exe</code>. I already checked on the powershell terminal that they are properly installed.<br>
  I tried the command <code>python3 -m venv .venv</code>. It created a <code>.venv</code> folder, but I get the following error message: <code>"Error: [Win Error2]  The system cannot find the file specified</code>.
  My IDE is Visual Studio Code 1.39.2</p>
  
  <p>Also, Python3 is added to path in the Variable environment <code>C:\Python\Python38</code></p>
  
  <p>I also tried to use the command <code>py -3 -m venv .venv</code>, but then I get:</p>
  
  <pre><code>Python 3 not found! Installed Pythons found by C:\WINDOWS\py.exe 
  launchers for Windows
  No Installed Pythons found
  </code></pre>
  
  <p>I also already executed the command <code>Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope Process</code> but nothing changed.</p>
  
  <p>My settings.json file:</p>
  
  <pre><code>{ "python;pythonPath": "C:\\Python\\Python38\\python3.exe" }
  </code></pre>
  
  <p>My pyvenv.cfg file:</p>
  
  <pre><code>home = C:\Python\Python38
  include-system-site-package = false
  version = 3.8.0
  </code></pre>
