Activate your GRE license from the command line (via internet)

If a Genero Report Engine (GRE) license has been installed, you can activate it using the command greWrt -k auto. The license is registered with Four Js via the internet and the installation and maintenance/subscription key is installed.

Internet is required

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

The license must be installed but not yet activated.

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.

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 .
At the command line enter the command:
```
greWrt -k auto 
```
When prompted, enter your customer code:
```
Enter your customer code > 
```
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 installation key and the maintenance/subscription key are installed automatically and the message is displayed.
```
Installing maintenance key 'MMMMMMMMMMMM'
License installation successful.
```
License installation is now completed.

Note:

There is no need to run greWrt -m auto to install the maintenance/subscription key.
