It's recommended to back up your Eggplant AI data before uninstalling Eggplant AI, especially if you want to migrate data across to Eggplant DAI by using the existing location as specified in step 4 below.

Tip: You can install Eggplant DAI 4.2.3 without uninstalling Eggplant DAI 4.1/4.0.1.

Installing Eggplant DAI

To perform a fresh installation of Eggplant DAI 4.2.3, follow these steps:

  1. Download the Eggplant DAI installation file from the Eggplant DAI Downloads page.
  2. Double-click the downloaded installation file to launch the Setup wizard. Click Next to begin installing Eggplant DAI. Note that you may be prompted to uninstall Eggplant AI if you haven't uninstalled it previously.
  3. On the Installation Directory screen, use the default installation directory (C:\Program Files\ Digital Automation Intelligence) or the file browser to select the desired installation directory. Click Next to continue your installation.
  4. Note: If you’re upgrading from Eggplant DAI 4.1/4.0.1, this screen will not be available.

  5. On the Advanced installer Options screen, select Run Advanced Install Configuration checkbox if you want to enable the option to specify ports, change the PostgreSQL data location, or specify Suite Data Directory and click Next to continue. Alternatively, leave this checkbox unselected to install Eggplant DAI as specified in step 8.
  6. On the PostgresSQL Data Directory screen, you might need to enter a path for the current installation of Eggplant DAI. Use the following information to decide whether this step is necessary for your installation:
    • If you're happy with the default path, then leave this field as-is.
    • lf you want to use a different directory, then add the path for the current application data (<install directory>/pgsql/data) by clicking the Choose Directory field.
    • If you want to configure the installer to use the Postgres data directory that was left behind after uninstalling Eggplant AI 3.1, then add the path of the previous installation folder (e.g., C:\eggplantAI\pgsql) by clicking the Choose Directory field.
  7. Click Next to continue to the next screen. When prompted, set the default HTTP port as follows:
    • If port 8000 is available, the installation suggests using port 8000. Click Next to continue.
    • If port 8000 is not available, you can enter the HTTP port you want to use.
  8. Leave the Report usage statistics checkbox selected to let Eggplant collect your usage statistics. Typically, the usage report will include: Product Identifier, Product Version, Host OS, Host OS Version, and License (Serial Number) information. You can disable this option by clearing the checkbox. Note that this option is only available if the Run Advanced Install Configuration checkbox is enabled.
  9. Specify the directory to point to the folder where you'd like your suites to be stored by browsing to that location and then click Next. This is the location where the agent will upload your suites to, which is also useful when running test configurations. Note that this is a completely different location to where you may be currently storing your Eggplant Functional suites.
  10. New feature: This screen is available in Eggplant DAI 4.1 and later.
  11. On the Select Start Menu Folder screen, if you want to use a different directory, browse to select it. Click Next to continue or Back to return and make changes.
  12. Note: If you’re upgrading from Eggplant DAI 4.1/4.0.1, this screen will not be shown.

  13. On the Ready to Install screen, click Install to begin installation. This installation step takes some time to complete.
  14. Click Finish to complete the installation.

See Licensing DAI to open Eggplant DAI and manage your Eggplant DAI licenses.

Configuring HTTPS in Eggplant DAI (Windows)

Eggplant DAI can be configured to support SSL/TLS by modifying the nginx configuration file that gets generated when you start Eggplant DAI. As the nginx configuration file gets generated each time you start Eggplant DAI, you must edit the python jinja2 template, which is used to generate the nginx.conf file itself. An example of modifying the template is described below.

Important: The modifications made directly to the python jinja2 file (nginx.conf.jinja2) will be overwritten whenever Eggplant DAI is installed or upgraded. Therefore, it is recommended to back up the copies of the changes you make to the nginx.conf.jinja2 file, the certificates, and CSR outside of installation directory.


Before configuring HTTPS, make sure you that the following prerequisites have been met:

  • Eggplant DAI is installed and running at least with one user who is able to successfully log in.
  • You should have obtained a trusted certificate and key. A trusted certificate is one that is issued by a Certificate Authority listed on the Mozilla page:
    • PEM format TLS certificate: For a list of valid certificates, see the Mozilla page.
    • PEM format TLS key: All key formats that are accepted by nginx.

Note: Eggplant DAI doesn't support self-signed certificates.

Step by Step: Configuring HTTPS in Eggplant DAI

  1. Stop the Digital Automation Intelligence service through the Windows Services manager. By default, it is set to automatically start after Eggplant DAI is installed.
  2. Locate the nginx.conf.jinja2 file in the installation directory:
  3. C:\Program Files\Digital Automation Intelligence\nginx.conf.jinja2

    Note: This file will be removed whenever you install, uninstall, and upgrade Eggplant DAI. Therefore, these steps will need to be repeated after each upgrade.

  4. To enable HTTPS, edit the section that shows the following settings with appropriate values:
  5. server {
    listen {{SERVER_PORT}};
    server_name localhost;
    #charset koi8-r;
  6. Add the server_name, ssl_certificate, ssl_certificate_key, and ssl_password_file (if required) values as shown below and then save it:
  7. server {

    listen {{SERVER_PORT}} default ssl;


    ssl_certificate C:Path/To/Certificate.file

    ssl_certificate_key C:/Path/To/Certificate.key

    # ssl_password_file C:/Path/To/Password.file; # depends on your configuration

    #charset koi8-r


  8. Restart the Digital Automation Intelligence service with the new configuration from the Windows Services panel.

Changing the Eggplant DAI Port on Windows

Although Eggplant DAI assigns port 8000 by default during installation, you can specify a different port later:

  1. Open C:\ProgramData\Eggplant\Digital Automation Intelligence\settings.ini.
    Important: The C:\ProgramData folder might not be initially visible, as it is hidden by default.
  2. Find the [settings] section and update the line server_port=8000 to include the port you want to use.
  3. Save your work.
  4. Restart the Digital Automation Intelligence Windows service.

Note: Any port changes made here should also be reflected in the Agent Server address section in your execution environment.

Upgrading from Eggplant DAI 4.1/4.0.1 to Eggplant DAI 4.2.3 on Windows

The upgrade steps for Eggplant DAI 4.2.3 are similar to installing Eggplant DAI except you'll be presented with fewer screens. Note that you must uninstall the previous agent and install a new agent from Eggplant DAI 4.2.3 to use the new features.

Upgrading from Eggplant AI 3.1 to Eggplant DAI 4.2.3 on Windows

If you're upgrading from Eggplant AI 3.1, then follow these steps after installing Eggplant DAI 4.2.3:

  1. Locate the Digital Automation Intelligence service in the Windows Services panel and stop it.
  2. Copy over all the Postgres data files and folders from your original location (e.g., C:\eggplantAI\pgsql\data) to the Eggplant DAI location (e.g., C:\ProgramData\Eggplant\Digital Automation Intelligence\data).
  3. Important:
    • The C:\ProgramData folder might not initially be visible because it is a hidden folder by default.
    • Copy all files and subfolders. When prompted, overwrite the existing files in the destination.

  4. From the Windows Services panel, start the Digital Automation Suite service.

Note: To configure the Eggplant DAI installer to use the Postgres data directory that was left behind after uninstalling Eggplant AI 3.1, choose C:\eggplantAI\pgsql when installing Eggplant DAI 4.2.3.

Uninstalling Eggplant DAI on Windows

Use the following instructions for uninstalling Eggplant DAI.

  1. Locate and run the Eggplant DAI uninstall program by choosing Start > All Programs > Uninstall Eggplant DAI.
  2. Click Yes when prompted to uninstall Eggplant DAI and all its components.
  3. Click OK after the removal process is done.

Uninstalling Eggplant DAI does leave some folders intact. Note that the data that's left behind after you uninstall Eggplant DAI contains user account information, user models, and execution data. Only remove these files and folders if they are no longer required. Assuming you installed Eggplant DAI in the C:/Program Files/ DAI directory, the following folders remain if you need to retain any files:

Eggplant DAI data directory files: C:\ProgramData\Eggplant\Digital Automation Intelligence\data

Server and Eggplant DAI log files: C:\ProgramData\Eggplant\Digital Automation Intelligence\logs

If you decide that you want to do a complete Eggplant DAI removal after following the above steps to uninstall Eggplant DAI, delete the following directory or folder:

C:\Program Files\Digital Automation Intelligence
