How Lectora License Keys and Activation Work

How Lectora License Keys and Activation Work

Get an overview of how Lectora license keys, product activations, and phone activations work. There are different license keys for each major release of Lectora but the product activation process is the same.

Types of Lectora License Keys

Lectora v12, v16, & v17 License Keys

License keys for Lectora Inspire and Lectora Publisher version 12 and up (v12, v16, & v17) are easier to read than our previous license keys. Lectora Inspire license keys for these versions will always begin “LI12“, “LI16“, or “LI17“. And Lectora Publisher license keys will always begin “LP12“, “LP16“, or “LP17“. This makes it much clearer which of your keys are for Inspire and which are for Publisher: the “LI” for Lectora Inspire and the “LP” for Lectora Publisher. Lectora 12 and up license keys are 15-17 characters long.

Older versions of Lectora (v11, vX, v2009, etc)

Older versions of Lectora do not have indicators for Inspire or Publisher. The license keys for older versions of Lectora are 12-14 characters long.


The Lectora End User License Agreement (EULA) licenses each license key of Lectora for install on one computer for use by a single user. Click here to view the EULA. Please contact Support if you need to install Lectora on both your desktop and laptop or home computer and work computer. We can manually release a spot for an additional product activation.


Each Lectora license key starts with a single, open product activation available. When you install Lectora it will activate you as a user on that license key in our database.


When you uninstall Lectora it will contact our database and remove your product activation. Then your license key is open to be activated again. If you need to move Lectora to a new computer or employee, just uninstall to release the activation and then install on the new computer. Your computer will need to have internet access to complete the deactivation. Please contact Support if your computer does not have internet access or is blocked from contacting our server when you uninstall.

“Run as Administrator” and Windows Account Permissions

Microsoft Windows user account permissions can be configured many, many ways. If you have trouble installing Lectora or see an error that Limited Users are not permitted to activate the software, it may be that your user account doesn’t have access to finish the installation correctly. Even if you have administrator privileges they may not exactly match up with what’s needed. Lectora, Snagit, and Camtasia need access to parts of the Windows Registry to properly complete the install.

The quickest way to resolve this is to right-click the Lectora installer and choose “Run as Administrator” from the menu. It may ask you to confirm the action or provide the administrator password. If Lectora is already installed, you can right-click the Lectora shortcut on your desktop and choose “Run as Administrator” if you are able to install Lectora but are blocked from activating it.

Error Message: The Maximum Number of Authorized Registrations for this serial number has been exceeded

If you see this error message when try to activate Lectora it means the software has been installed on another computer and all of the allowed activations are already in use. You will need to uninstall Lectora from the other computer before you can activate it on your computer.

Phone Activation

If your computer does not have access to the internet or Lectora is blocked from contacting our server to activate we can perform a phone activation instead. Please contact Support and we will arrange to complete the activation over the phone. Clicking the “Activate by phone” link at the bottom of the activation window will generate a “Request Key”. When you give your “Request Key” to Support we will give you back an “Authorization Key” that you can enter into the form. Lectora will generate a new “Request Key” each time it is launched.
