Install or update GRE maintenance/subscription key from command line (via internet)

You can install or update the maintenance/subscription key of your Genero Report Engine (GRE) product using the command, greWrt -m auto. During installation the key is retrieved from Four Js via the internet.

Internet is required

Before you begin: Internet access is required to activate the license; a temporary installation does not require internet.

Important:

If your installation directory is in the C:\Program Files path, you must run as administrator when you license the product. This avoids any permission issues.

  1. Start the command line interface.
    Open a command prompt.
    • On Linux®/UNIX®/macOS™, open a command prompt. "sudo" may be required.
    • On Windows®, open the Command Prompt window from the Start menu.
  2. At the command line enter the command:
    greWrt -m auto  
  3. When prompted, enter your customer code:
    Enter your customer code > 
  4. At the following prompt:
    Do you need to configure an HTTP proxy ? (y/n)
    Enter y if your access to the internet is through a proxy. Provide the required information for HTTP proxy, port, and authentication when prompted. Otherwise, enter n.
    The maintenance/subscription key is then retrieved from the Four Js Activation server and a message is displayed:
    Maintenance key installation successful.
