Besides
interfacing with the application for automatic software update, you can also
build the Updater as an Online Installer that can run individually. The Online
Installer is a small program with embedded script files that can automatically
download the setup file and execute it to perform software installation. The
Online Installer can also perform automatic update to check for the new
software version.
The Online
Installer (and Updater) includes the download resume capability that is
especially needed for downloading large setup files. It can resume unfinished
download due to any reason such as lost connections, slow servers, computer
shutdowns, etc. The resume capability can restart the download in the middle, without
having to restart all over again.
You can
build the Online Installer by using UpdateShield
Builder, which you can specify the options and include
your script files. The created Online Installer is a single EXE file with the
embedded Client Side index file and script files. When the Online Installer
finishes downloading, the embedded script files will be extracted and run
automatically in the folder of the downloaded file.
