title: Can't uninstall Python 2.7.11, have I screwed up everything?
body: <p>I'm an anaconda user, but I had to install python 3 a while back in order to use PIP to install a module for whatever reason. And I also had installed python 2.7 but completely forgot about it. Of course, a whole bunch of issues sprouted up from this, namely when trying to run scripts out of the IDLE. </p>
  
  <p>This is the issue that pops up:</p>
  
  <blockquote>
    <p>There is a problem with this Windows Installer package. A program run
    as part of the setup did not finish as expected. Contact your support
    personnel or package vendor.</p>
  </blockquote>
  
  <p>I downloaded the python 2.7 installer and tried reinstalling it and changing the installation, though that process went smoothly, nothing changed.</p>
  
  <p>The previous answers say that python 3 and anaconda should be uninstalled, which I've done, but the problem persists. What do?</p>
