Step-by-step guide: How to deactivate a named license of HelpNDoc
Named licenses can only be installed on a limited number of computers you own. If you need to move your license to another computer, you'll need to deactivate it first from the old computer before activating it on the new one.
Launch HelpNDoc on the computer where it needs to be deactivated, and click the "File" menu.
Click the "Help" tab to access license details.
Click the "Manage license..." button in the "License details" section.
Confirm that you want to deactivate your license on this computer.
HelpNDoc is now deactivated on this computer. It is therefore possible to activate it on another computer.
