Silent Installation Behavior when using InstallAnywhere

Silent Installation Behavior when using InstallAnywhere

Summary

This article describes the normal silent installation behavior and clarifies what user should expect to see if installation is launched in silent mode.

Synopsis

This article describes the normal silent installation behavior and clarifies what user should expect to see if installation is launched in silent mode.


Discussion

InstallAnywhere installers can be run in three different user interface modes: GUI, Console and Silent. Installers that have the Silent option enabled in the section, Installer UI>Look & Feel>General UI Settings>Allowable UI Modes, can be run in Silent mode using the following command:

install ?i silent 

where ?install? is the installer launcher built after the build process is complete.
Silent mode installation doesn?t result in any user interaction. Unlike GUI and console mode installations, if an installer is run in silent mode, no output is sent to the console screen. Upon launching the installer in silent mode in Linux, the user will see the blinking cursor in the console screen until the install is complete and returns to the next prompt in the screen.

User-added image
For Windows installer, launching the silent installation from command prompt results in two different behaviors depending on what type of launcher is selected. For this information, refer to the KB article Q202863 mentioned in the Additional Information Section below.
In versions of IA prior to InstallAnywhere 2010 SP1, running the installer in silent mode sent output to the console window in both Windows (when using console launcher type) and Linux machines (as shown below), which was not the expected behavior.

User-added image
This was corrected and addressed in InstallAnywhere 2010 SP1 and versions thereafter. One should run the installer in Console mode or GUI mode for installations that require any kind of user interaction.
