Why a Customized PDF Reader Pro is Needed?

Typically, when activating PDF Reader Pro using the installation package downloaded from the official website, the software will make an activation request to the official website.

In the on-premise environment, the software will request activation from the on-premise server deployed within the enterprise.

Therefore, for the software in the on-premise environment, the domain name used by the enterprise's on-premise server needs to be included in the package.
