title: Why does WinRAR stall indefinitely after creating the archive?
body: <p>Using WinRAR 4.2 64-bit to create password-protected archive files, launched via WScript.Shell Exec method using the command line:</p>
  
  <pre><code>C:/Program Files/WinRAR/rar.exe a -df -ep -pxxxx C:/mtr_app/output/local/REP025_Secondary_Aug-2016.rar C:/mtr_app/temp/47/*.*
  </code></pre>
  
  <p>This works fine usually but fails to finish with a particular archive comprising about 40 files (39 Excel and 1 text).  The archive is created within a few seconds and then WinRAR just doesn't exit.  This is repeatable, but only with this particular (large) archive.  The '47' directory in the command line is a temp directory created specifically to hold the files required in the archive, so it gets a different number each time (a job id).</p>
  
  <p>WinRAR is correctly licensed, but in any case its correct behaviour with other archives seems to rule out the hidden EULA window gotcha.</p>
  
  <p>Any suggestions would be welcome.</p>
