I had the same problem recently with subprocess.popen, when there is a
space in the executable and a space in an additional argument as in
the acrobat example. I finally found a past thread in this news group
that explained that you have to use two (2) leading double quotes, and
as on the command line all arguments with spaces have to be quoted.
All three examples with acrobat work on my WindowsXP in this case
(opens Acrobat three times, after closing previous):
<code>
import os
import subprocess
filename = r"C:\Program Files\Adobe\Acrobat 7.0\Acrobat\Acrobat.exe"
doc = r"C:\Program Files\Adobe\Acrobat 7.0\Help\ENU\Pdfmark.pdf"
print os.path.isfile (filename)
print 'case 1'
os.system ('""' + filename + '" "' + doc + '"') # quotes split up for
clarity: (' " " ' + filename + ' " " ' + doc + ' " ')
print 'case 2'
os.system ('""%s" "%s"' % (filename, doc))
print 'case 3'
subprocess.call ([filename, doc])
</code>
