License GRE from the command line (no internet)

Without internet access, you register the license with Four Js from another machine via the internet, or by phone. Then use the greWrt command line tool to license your Genero Report Engine (GRE) product.

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.

Tip:

Run the envgre script before starting. This ensures that the installation environment for Genero Report Engine is set. For further information, see Installation conventions.

If you are not provided with a license string, you can generate a license string from your license number, license key, maintenance/subscription key, and login. For instructions on how to generate a license string, go to Encode a license string.
