Actuate does not support running multiple releases from the same version on a machine. For example, you cannot run iServer Release 11 Service Pack 3 and Release 11 Service Pack 4 on the same machine. Actuate also does not support running BIRT iHub on the same machine as any iServer Release 11 version.

A BIRT iHub can coexist on the same machine with an earlier major release, such as Release 10 Service Pack 1. To run different iServer major releases on the same machine, install the releases in separate directories. Change the default port settings for one release to enable running both versions at the same time.
