[KB8154] Resolve Error 1603 during Live Installer package installation for ESET PROTECT

Issue

• Resolve "Error 1603: A fatal error occurred during installation" that displays when you install the Live Installer package from ESET PROTECT on a client computer
• Download and install ESET Management Agent and the security product separately
• Create the install_config.ini configuration script that contains the parameters for the Agent to communicate with your ESET PROTECT Server

Solution

1. Open ESET PROTECT in your web browser and log in.

2. Click Quick Links → Windows device. 

   

3. Click Customize installer. 

   

4. Select Use GPO or SCCM for deployment and click Finish.

   

5. Click Configuration GPO/SCCM script → Finish.

   

6. Download the ESET Management Agent installer .msi file from the ESET download page.

7. On the client computer, create a new folder and save the Agent installer .msi file and the install_config.ini file to that folder.

8. Double-click the Agent installer .msi file to begin the ESET Management Agent installation. The installer will automatically use the information from the install_config.ini file.

9. When the installation is done, verify the client computer is in the ESET PROTECT Web Console. If you still see Error 1603, troubleshoot ESET Management Agent further. 

10. Deploy the ESET endpoint products using an installation task in ESET PROTECT or download and install the endpoint product from the ESET download page.

    Ensure your operating system is fully updated and you have manually uninstalled previous versions of ESET security products. Resolve common ESET installation error messages.
