Shyam,

After looking at your comments and making some additions to my
notebooks, I concur with your assessment; I believe there are problems
with space handling in Run.

Here are some examples:
http://chris.chiasson.name/Mathematica/mg66048
http://chris.chiasson.name/Mathematica/mg66048_with_space_in_path

For others, note that an exit error level of zero indicates success,
while an exit error of 1 indicates failure.

If you don't have a premier support account, send me a separate
message and I will file a bug report.

Regards,
