Had this been on Unix, you'd either get "file not found" or similar from the shell trying to run the thing, or something from xplanet itself (only really badly programs return failure without printing some kind of cause). Two more comments, assuming you are on Windows (you mention ".bat files"): - You use the relative path xplanet-1.2.0/xplanet.exe. That should require your program to have the parent of xplanet-1.2.0 as current directory. Did the .bat script change directory first? - It is unusual to use / as a path separator on Windows -- xplanet-1.2.0\xplanet.exe is more normal. Some parts of Windows tolerate both, others do not, IIRC. But Python itself should not care in this case. /Jorgen -- // Jorgen Grahn <grahn@ Ph'nglui mglw'nafh Cthulhu \X/ snipabacken.dyndns.org> R'lyeh wgah'nagl fhtagn! -- http://mail.python.org/mailman/listinfo/python-list
