License GRE from the command line (via internet)

You can license a Genero Report Engine (GRE) product using the command line tool, greWrt.

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.

Tip:

Run the envgre script before starting. This ensures that the installation environment for Genero Report Engine is set.

Which procedure should I follow?

To install your license, you must have either a license string, or you must have your license number, license key, and your customer login.

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