You should be able to just add your executable to the "files" array and 
have it transferred along with your other input files.

This depends on your Condor configuration. By default, I believe, Condor 
will try to run your program as if it were the user you specified in the 
Owner attribute of your job. If the owner does not exist you probably 
don't see the log because your job is not running.

You need to have the owner exist as a user on the execute machine or 
configure Condor to use nobody users.
