title: How to test if a windows group exists from inno setup?
body: <p>How can you test to see if a windows group is already setup? Can you somehow use the response from: </p>
  
  <pre><code>Exec('net.exe', 'localgroup', '', SW_SHOW, ewWaitUntilTerminated, Result);
  </code></pre>
  
  <p>which will list the groups to the command prompt?  (I know that Result is an error code where 0 is success, just to be clear.) </p>
  
  <p>Is there a way? Is there more than one way?</p>
