Silent Enterprise Control Room installation, also known as unattended installation, uses a customized script for a full setup or the command line for a hot fix patch. Silent install runs the entire installation process in the background without requiring user interaction or displaying messages.

2. Option: Edit the sample script to use an Microsoft SQL Server database.
   Use the script to install the Enterprise Control Room with the configuration options available in the installer.
   1. Correct values for variables such as: $service_username, $service_pwd, $db_server, $cr_port.
   2. Run the script with a Credentials in Service logon, and a non-secure connection using Microsoft SQL Server authentication with a new database.
   Sample script:

   $cr_port=80
   
   $service_username= "domain\username" #e.g."aaspl-brd\ellie.brown"
   $service_pwd="password"
   
   #$certpath = "C:\SilentInstall\test256.pfx"
   #$certpass = "changeit"

   If installation is not proper check msi logs in the temp folder.
   pause

3. Save the script you edit to the server for installation.
4. On the installation server, logged on as an Administrator, open Powershell in admin mode and execute:
   Set-ExecutionPolicy Unrestricted -Scope CurrentUser -Force
5. Start Powershell in admin mode and execute:
   .\install.ps1

   Note: The silent install logs are stored in the folder from which the install script is executed. For example, if you run the script from C:\Silent Install, the logs are stored in C:\Silent Install folder.
