To supply form designs to LiveCycle Forms ES, you will need write access to the location from which LiveCycle Forms ES retrieves files at run time. The developer of the custom application will know the location, and your network administrator can set up the appropriate permissions.
Completed form designs are placed in the local file system for the developer of the custom application to access. You have to include any other files that are required to support the form design (for example, images).
