You can change your access decision at any time. If you install multiple products together, you can use different locations for the help for each product, depending on installation footprint, frequency of use, and internet policies. If internet speed is an issue, a longer one-time download and local access might be preferable. Later help updates include only differences.
If you are an administrator and you want users to access help content from an intranet server, see the Installation Manager information center for instructions on how to install the help WAR file on a server. In the Installation Manager information center, select Installing and upgrading->Enterprise installation articles -> Delivering help content from an intranet server.
