Executing Packages On SQL Server MSDB From Visual Studio Project

I created several packages (MyProjectPart1 - MyProjectPart9) which I execute on the server directly(right-click package in integration services and execute). These packages alI deployed the server with logging and configuration files. Before deploying I edited the configuration file (changed all dependent file names and sql server name from default on my workstation to those unique to the server I'm deploying it to) and then ran the manifest file which pushed it onto the server. I then ran the packages from the server an it ran beautifully. I then tried to build a package which executes all the packages in the correct order (by adding 9 execute package tasks). The dependen files are on the E: emp folder on the server.


I have included the error messg...but it looks like it's looking for dependent drives on the C drive on my workstation. I don't get this? How do I supply configuration files? Why is it executing differently when I call it from package execute task and when I execute it on SQL Server
