title: Git Extensions "function not implemented"
body: <p>I'm trying to use <a href="https://gitextensions.github.io/" rel="noreferrer">Git Extensions</a> on a new Windows 7 machine. I have done that many times before but never hit this particular issue.</p>
  
  <p>Git Bash is working, I successfully cloned a repository.</p>
  
  <p>But going to Git Extensions, opening the repo, and doing a pull gives me the following error message:</p>
  
  <pre><code>"C:\Program Files (x86)\Git\bin\git.exe" pull --progress "origin"
  error: cannot spawn git: Function not implemented
  Done
  
  Press Enter or Esc to close console...
  </code></pre>
  
  <p>My setup is very ordinary. The Git Extensions startup checks all pass. (This is similar but not the same problem as the common invalid path issue.)</p>
  
  <p>Do you have any idea what causes this problem?</p>
