Uninstall license from command line

Use the greWrt -d command to uninstall your Genero Report Engine (GRE) product license.

Before you begin: You must be the root user or the user who installed the software, to run the license controller command.

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.
From a command prompt, enter the license controller command.
greWrt -d
At the prompt:
Do you really want to uninstall the license (y/n)?
Enter: y
The license is uninstalled. A message confirms the license is uninstalled.
