SSIS Job deployment does not run my .exe but is described as a success

Question

Hi i have scripted a simple script task in c# to run an exe with the following code
Process.start(filename.exe);
i have also tried using the 'Execute Process task' in the SSIS toolbox.
both methods work when i debug. 
However when deployed to the SQL server as a job, the jobs are described as a success but my program does not run?!
The exe file is published from SQL visual studio and the resultant filename is setup.exe which i am trying to run.
Any help pleasE?
I am not using any shared file resources, the setup.exe is on my desktop.
