# Installation and Upgrade Guide

# Silent Properties File

When you install Collaboration, the installer creates the file AquaLogicInteractionCollaboration_<version>_silent.properties in the directory where Collaboration is installed. Once you have created a silent properties file on one computer, you can reuse it when you install Collaboration on other computers, so that you do not have to re-enter deployment information every time you use the installer. During a "silent" install, the information required by the installation dialogs is read from the properties file.

A silent install may be run from the command line as follows:

    ALICollaboration_<version> - f AquaLogicInteractionCollaboration_<version>_silent.properties

For example:

    ALICollaboration_v4-1 - f
    AquaLogicInteractionCollaboration_v4-1_silent.properties

A silent install can be useful for distribution of the product across a uniform set of machines.
