title: python error can't open pdf in application from python
body: <p>I am using windows 10 and python 2.7.13 .
  My target is to open a pdf in acrobat reader at a specific page number.
  I am using the code I received from one of the questions in the forum here.</p>
  
  <pre><code>import subprocess
  import os
  
  path_to_pdf = os.path.abspath('C:\test_file.pdf')
  # I am testing this on my Windows Install machine
  path_to_acrobat = os.path.abspath('C:\Program Files (x86)\Adobe\Reader 10.0\Reader\AcroRd32.exe') 
  
  # this will open your document on page 12
  process = subprocess.Popen([path_to_acrobat, '/A', 'page=12', path_to_pdf], shell=False, stdout=subprocess.PIPE)
  process.wait()
  </code></pre>
  
  <p>It opens up the acrobat reader application but the file doesnt open and i get the error :<strong>"There was an error opening this document. The filename, directory name, or volume label syntax is incorrect</strong></p>
  
  <p>but when I use these commands in cmd without python I am successfully able to open the pdf without any error. Please help.</p>
