InstallScript Multi-Instance Setup

InstallScript Multi-Instance Setup

Summary

Information about the InstallScript project and Multi-Instance support in a user interface

Synopsis

Based on Maintenance Experience Settings the InstallScript project type offers several options for the behavior of your installation when a target machine already has your product installed and the end user reruns the installation. The multi-instance option lets your end users rerun an installation multiple times as a first-time installation rather than as a maintenance installation.

Discussion

When instances of your product are present on a client and an end user reruns the InstallScript multi-instance installation with a user interface, the installation displays the Qualifying Product(s) Detected dialog. This dialog enables the end user to select a new instance of install or to which instance the update should be applied.

To establish a multi-instance install in an InstallScript project

1) Use the General area of the General Information view to specify Maintenance Experience Multi-Instance
2) Complete creation of project, build and test the user interface
3) Rerun an installation multiple times to experience the User Interface
