title: python launchers (.exe) from \script fails
body: <p>I'm trying to convert QT .ui file into .py file.</p>
  <p>Found several issues saying &quot;.exe's won't run from a directory with spaces&quot;.
  I was struggling with the same issue, and found that there were multiple copies of .exe file on my drive.</p>
  <blockquote>
  <p>C:\shbaek&gt;where.exe pyuic5</p>
  <p>C:\Program Files\Miniconda3\Scripts\pyuic5.exe</p>
  <p>C:\Users\MSOlab\Miniconda3\Scripts\pyuic5.exe</p>
  <p>C:\Users\MSOlab\Miniconda3\Library\bin\pyuic5.bat</p>
  </blockquote>
  <p>And I was running the command line as Administrator, so calling pyuic5 would access the one from \Program Files\. When I directly change directory to second one and run pyuic5, it runs without any error but the first one would give an error massage as follows.</p>
  <blockquote>
  <p>Fatal error in launcher: Unable to create process using '&quot;'</p>
  </blockquote>
  <p>Running the prompt without Admin privilege automatically runs the second one (from \Users\) without any error.</p>
  <hr />
  <p>So, am I supposed to run cmd without Admin privilege to avoid those issues? Or is there any possible way to force the Admin cmd run pyuic5 from the \Users\ path?</p>
