An Enablement Service Pack is used to improve your efficiency in developing, publishing and deploying content for your audience.  The ESPs may contain new features, updated capabilities and fixes to problems.

The ESP installer will determine the configuration to update based on the location you specify. If you are planning to update both the Developer and Knowledge Center, you will have to run the ESP installer twice. If you have multiple instances of both the Developer and Knowledge Center installed, the default path will be the last installed instance of either the Developer or Knowledge Center. You must run the ESP installer multiple times update each instance.

The recommended order to apply a service pack to the Developer is as follows:

1. Apply the service pack to the Developer Server.
2. Apply the service pack to one Developer Client.
3. Launch the Developer Client to update the library.
4. Apply the service pack to all other Developer Clients.

The recommended order to apply a service pack to Knowledge Center is as follows:

1. Apply the service pack to the Knowledge Center Server.
2. Apply the service pack to the Knowledge Center User Import Utility.
