How can you activate a license on an installation in a closed network without internet access?

Activating a license on an installation in a closed network without internet access can be achieved by exporting a License Request File. This process involves generating a file on the system where the software is installed. Since the network does not have internet connectivity, this file can then be taken to a separate machine that does have internet access, allowing the user to obtain the necessary activation information or license key from the licensing authority.

Once the activation information is received, it can be imported back into the closed network system, completing the activation process without needing direct access to the internet during the activation itself. This method is commonly used in secure environments where maintaining network isolation is essential.

The other options revolve around different methods of activation that are not suitable for a closed network scenario. Online activation requires direct internet access, the administrator tool does not facilitate offline activation processes, and reinstalling the software does not inherently solve the licensing issue. Thus, the approach of utilizing a License Request File is specifically designed to handle licensing in restricted environments effectively.
