When executing the following code snippet

import process
for x in Files:
Command_String = 'C:\Program Files\WinRK\WinRK.exe -create ' +
os.path.join(InputDirectory, os.path.splitext(x)[0]) + ' -set
compression_method ppmz -setg include_paths none -add ' +
os.path.join(InputDirectory, x) + ' -apply -quit'
PROC = process.Process(Command_String)

from the command line

C:\Documents and Settings\eeiland\Desktop>Thesis_Programs\Compresso
ta\sliceX12 Test_Output\Test

generates the following error:

Traceback (most recent call last):
File "C:\Documents and
", line 61, in ?
PROC = process.Process(Command_String)
File "C:\Python24\Lib\site-packages\", line 839, in __init__
