  <p>I have looked at several stack overflow threads like this one:</p>
  <p><a href="https://stackoverflow.com/questions/41530269/error-end-of-central-directory-record-signature-not-found-while-installing-ion">Error &quot;end of central directory record signature not found&quot; while installing ionide-fsharp in vscode</a></p>
  <p>I can confirm the following:</p>
  <ol>
  <li>My company runs a corporate transparent proxy, so I do not have to enter a proxy in the settings.  I've confirmed that I do not have this set.</li>
  <li>I have followed the instructions to download and install the vsix file manually
  <ul>
  <li>Downloading looks to be successful, the python extension is 16.5 MB</li>
  <li>The installation portion of the downloaded file fails with the same error</li>
  <li>Confirmed that I do not have a disk space issues as someone mentioned in the above thread</li>
  </ul>
  </li>
  <li>I have reinstalled VSCode per these instructions: <a href="https://stackoverflow.com/questions/42603103/how-to-completely-uninstall-vscode-on-mac">How to completely uninstall vscode on mac</a>
  <ul>
  <li>I've attempted installations of VSCode 1.59 (original version) and 1.58.2, same errors</li>
  </ul>
  </li>
  </ol>
  <p>Any suggestions on where to go from here?  I'm not able to install this locally, and can't seem to figure out what may be causing the issue.</p>
  <p>I have confirmed with other team members that they're not running into my issue, and they have successfully upgraded to Big Sur.  I don't think that's the cause, but that's the only change to my workstation that I can think of.</p>
