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

You can install or update the maintenance or 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 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 key is then retrieved from the Four Js Activation server and a message is displayed:
    Maintenance key installation successful.
