Sorry, I wasn't clear enough - I am not trying to execute packages, I want to execute whole projects. Each project will have packages within it, deployed as a project. The project will have a SQL Agent job written for it that I can execute within another project, a 'master' project if you like that controls precedence and dependancies of project executions, but sql agent job execution in SSIS doesn't wait until the job is complete until it moves to the next package, it executes them all in very quick succession, asynchronously. Thats my issue!
