An important feature of LizaJet Installer is that user dialogs can be shown before the downloading of the application. This reduces the psychological waiting time for your end-users, and respects their attention-span.

The user must download and run your small setup program. Because it is 170Kb, the user can run it nearly immediately.
The first step of the setup program is to download and install the LizaJet Engine.  If it is already installed this step is skipped.
Directly after that moment the first user dialog will start.

Only after filling in the dialogs, the download of the application start.
If the user decides to exit  the download process, the next time the computer starts the download is automatically finished and the program is installed.

With this approach we have maximized the usability of the software, and minimized the chance of not finished installations of your software.
