Use the installer to automatically install and configure Talend Remote Engine.

## Procedure

1. Run the installer file as an administrator.
2. Select the region of your Talend Cloud account.

   The region is reflected in your Talend Cloud URL following this pattern: <region>.cloud.talend.com. For example, if your URL is us.cloud.talend.com, select AWS - USA East as your region.

   More information in [Accessing Talend Cloud applications](https://help.qlik.com/talend/en-US/installation-guide-windows/Cloud/talend-cloud-application-url) with a list of the URLs to use for each data center.
3. Paste the Remote Engine Key generated in Talend Management Console when you create the Remote Engine into the Preauthorized key box.
   ### Example

4. Optional: Select the Install as a system service checkbox to make Remote Engine a service of your system.

   If you skip this step, you can still install your engine as a system service later by following [Setting up Remote Engine service manually](https://help.qlik.com/talend/en-US/installation-guide-windows/Cloud/setting-up-remote-engine-service-manually-t).
5. Optional: For Talend Remote Engine v2.13.9 and onwards, select the Separate Java for non Java 17 compliant job/microservices (Java 8/11) checkbox to configure a separate Java instance to execute artifacts requiring Java 8 or 11. Then in the JAVA\_HOME field, enter the path to that Java instance, for example, C:\Java\jdk-11.

   The installer automatically activates [the JVM adaptive mode](https://help.qlik.com/talend/en-US/talend-glossary/Cloud/jvm-adaptive-mode) for the engine by setting the following properties for artifact executions:
   * When the checkbox is selected, the installer adds the engine-startup Java in the <RE\_installation>/etc/system.properties file.

     Information noteImportant: On Talend Remote Engine v2.13.9, Java 17 is required for engine startup. From v2.14.0, Java 17 or Java 21 can be used.
   * When the checkbox is selected, the installer additionally sets org.talend.execution.JAVA\_8\_PATH or org.talend.execution.JAVA\_11\_PATH in the <RE\_installation>/etc/system.properties file, depending on the Java instance specified in the JAVA\_HOME field.
   * If you leave this checkbox clear, only the engine-startup Java is used for artifact executions.

   You can always change the configuration after the installation by modifying the <RE\_installation>/etc/system.properties file. To do this, follow [these steps](https://help.qlik.com/talend/en-US/remote-engine-user-guide-windows/Cloud/configure-java-versions-for-job-execution-or-microservice-execution#configure-dynamic-adaptive-jvm-versions-for-job-execution-or-microservice-execution).
6. Optional: Select the Use HTTP proxy checkbox and enter the server and port details.
7. Optional: Select the Use Proxy Authentication checkbox and enter the user credentials.
   ### Example

8. Optional: Select the Set strong password for default SSH user checkbox to automatically create a strong password for SSH communication with Talend Remote Engine. Otherwise, tadmin is used.

   For further information about how SSH is configured for your engine, see [Changing the auto-generated default SSH password](https://help.qlik.com/talend/en-US/remote-engine-user-guide-windows/Cloud/enabling-remote-access-using-ssh-optional#changing-default-ssh-password).
9. Optional: Select the Use SSL for JobServer communication checkbox to automatically secure the communication between Talend Remote Engine and its JobServer.

   For further information about how SSL is set up for Talend Remote Engine, see [Enabling SSL communication for your Remote Engine](https://help.qlik.com/talend/en-US/remote-engine-user-guide-windows/Cloud/enabling-ssl-connection).
10. Finish the installation by following the steps in the wizard.
