Will the latest UPDATE installer update all previouis versions of the satellite to the latest release?


Nope. Unless otherwise noted, updates only update satellites previously installed with the same major release #.

For example, if you had the version 2.0 satellite installed on your computer, you could get the version 2.1 updater and use it to bring you up to the latest software.

However, if you had a 1.x version of the satellite installed, the version 2.1 updater would not work.
