   ![](https://help.qlik.com/talend/en-US/change-data-capture-installation-guide/Resources/images/tcdc-OS-support-for-installation.png)
   * Step 1: Make sure your source database(s) are installed and configured on the OS of your choice, according to [Hardware and software requirements for source databases](https://help.qlik.com/talend/en-US/change-data-capture-installation-guide/7.3/tcdc-hardware-software-reqs-source).
   * Step 2: Install Talend Change Data Capture Manager GUI on [Installing the Manager GUI and its modules on Windows NT Server](https://help.qlik.com/talend/en-US/change-data-capture-installation-guide/7.3/installing-on-windows) and the [Installing the source engines on Windows NT](https://help.qlik.com/talend/en-US/change-data-capture-installation-guide/7.3/installing-the-source-engines).

     Information noteNote: The Manager and the source databases can be installed on the same machine or on separate ones.
   * Step 3: If they were not already installed at Step 1, install and configure your target database(s) on the OS of your choice, according to [Hardware and software requirements for target databases](https://help.qlik.com/talend/en-US/change-data-capture-installation-guide/7.3/tcdc-hardware-software-reqs-target).
   * Step 4: Make sure port 1310 allows inbound and outbound communications on the Manager and the engine machines.

     Information noteWarning: For security reasons, make sure your machines are in a private network (LAN or VLAN for example).
2. To install your Talend product, you need to download your license key file and the relevant software packages:
   * Your personal license key that you received by email.

     This file has no file extension, and it is required to access each Talend module. Keep this file in a safe place.

     You will need it when [Under 7.16.1 version: fields completion](https://help.qlik.com/talend/en-US/change-data-capture-installation-guide/7.3/adding-license-prior-7161)

   * The software packages that correspond to the Talend Change Data Capture modules you need to install.

     * Setup.exe for the installation on Windows.
     * SetupAS.exe for the installation on AS/400 IBMi.
