If you do "GetEnv = True" in your job submit file, your job will end up 
with the same set of environment variables (incl path) that is visible 
to "condor_submit" on your submit machine.

When HTCondor runs a job, indeed it will by default scrub the 
environment of the execute machine.  If you want the environment 
variables of the execute machine to be visible to the job, in the 
condor_config file on the execute machines set
  JOB_INHERITS_STARTER_ENVIRONMENT = True
[ See 
http://research.cs.wisc.edu/htcondor/manual/v7.8/3_3Configuration.html#19939 
]

On Windows, be aware there are two sets of environment variables: system 
environment variables that are in common across all users, and user 
environment variables that are specific to a given login.  Hopefully 
your application is installed "for all users" and thus has populated the 
system environment....

Hope the above helps
Todd
