The days of when you could limit yourself to creating a single executable are ages ago. Now users expect more, in their view a professional installation must at least enable them to:

• Only download and run an initial setup program

  

  The action is executed when your application is installed the first time.

  

  The action is executed when your application is upgraded.

  

  The action is executed at first installaton and when upgrading.

  , so they quickly can start with the installation
• Download only the necessary files
• Automatic upgrade when a new version of your software is available.
• Automatic repair when necessary

Integrated framework
With LizaJet Installer all functions are already included and are part of one integrated framework. During installation and upgrading the installation engine executes Actions in the sequence you define. And at each action you can define if the action must be executed at first installation, when upgrading or in both situations.

You no longer have to buy extensions to your system. And you do not have to spend time in mastering two different systems and try to integrate them. 

Your end-users will no longer wonder why you provide them with two different systems: one for installation and another one upgrading.

The initial setup program is really small, and contains everything necessary to fetch the LizaJet Engine (if it is not already installed) and your application.  It includes its own download manager, and it can contain your digital signature. 

The initial setup program is only 134 Kb, your users can start installing within a few seconds of downloading your installation program
