title: pyInstaller exe failed because it did not include a module
body: <p>Situation: Building an EXE from a python script that encrypts things.</p>
  
  <p>Problem: The EXE always fails as it cannot find modules that I have imported (<code>Crypto</code>).</p>
  
  <p>Question: Is there a flag I need to turn on or include to make sure that pyInstaller includes <code>Crypto</code> when building the EXE?</p>
  
  <p>Additional information: The <code>Crypto</code> here refers to <code>pycryptodome</code></p>
