We have a all Windows Condor pool, and Python (2.3 and 2.4) jobs have
been executed without problems.  I repeat your submission file, DOS
batch file, and simple "Hello, World" Python script, and they work
okay in our pool.

This part is different from the StarterLog we have seen here (we use
Condor 6.6.10).  Here is a snippet of the StarterLog on the execution
machine,

The main difference is that when Condor sees the executable is a .bat
file, it invokes Windows shell.  However, according to your log,
Condor, for some reasons, still tries to run an executable .exe.  You
may want to turn on the debug flag on Starter to see what's going on.
