Nitro Pro Activation Certificate

To continue using Nitro Pro after the trial period has expired, it is necessary to purchase a license that must be activated on your computer.

Activation ensures that you have bought a genuine Nitro product by linking the software license to the computer on which it is installed.

  • The following key terms will be used throughout this help topic:.
  • Serial: a number that is unique to your license of Nitro Pro.

Activation: a software process that validates the authenticity of your Nitro Pro installation to protect it from being used by someone else on other computers (the number of activations permitted for your serial depends on the license you purchased).

Computer ID: a unique hardware identification number derived from your computer’s physical components. Installation ID: a unique identification number derived from a combination of your serial and computer ID.

Deactivation: the process that disassociates your serial from your computer and enables you to install Nitro Pro on another machine.

  • Certificate-based security has many advantages over password-based security: documents can be opened without the need to remember passwords, Digital IDs cannot be shared or copied easily, the one document can contain different security settings for each recipient of a file.
  • For example, you may grant one person editing and printing privileges, while another is limited to just viewing the file.
