It's a good idea to specify the absolute paths for any commands or output
files.

Hmm, looks like it *is* getting executed, but the output is lost?  See
the previous comment.

Can you execute the latter script from the command line as Administrator?
If not, are the access permissions on both *paths* sufficient?  For a
script to be executable, all the components in the path to it have to be
reachable (i.e., the directories have to have at least the execute
permission).

This is a different symptom -- most likely the necessary DLLs in your /bin
are not executable by non-owners (i.e., SYSTEM, which is the user cron
will run under when installed as service).  A "chmod -R a+X /bin" should
help (you might also need to fix permissions for other files/directories
under /var, and maybe /lib, /share, and /etc).
