Prior to launching the Talend Installer, check that:
you have downloaded a Talend-Tools-Installer-YYYYYYYY_YYYY-VA.B.C-installer.zip holding a folder.
In the folder that you will extract, you will find a dist file and executable files corresponding to the supported operating systems.
In the file name, YYYYYYYY_YYYY is the timestamp and A.B.C is the revision level (Major.Minor.Patch).
The dist file is only required to install Talend products. Once the installation and configuration is complete, you can remove it.
the following software and modules are properly set up on the station where you are to install the Talend modules:
JRE 1.8.0 or higher must be installed on your machine;
(optional) a mail server (to send notifications by email).
Talend Installer allows you to get out-of-the-box Talend solutions that do not require any manual installation. However, these solutions are not provided in a production-ready environment as they may require additional configurations or optimizations according to your specific needs.
For example, you may want to change the H2 database that is embedded by default in Talend Administration Center with your own database (MySQL or Oracle for example). If you do this, you need to install the driver for the relevant database. For more information, see, Installing database drivers in your Web application server.
