Activation error message - license cannot be found

[DeJuana Jernigan]

I recently got a new laptop and have followed the instructions for deactivating on old laptop but when I attempt to activate on new laptop I receive a message indicating the license cannot be found.

Hello @DeJuana Jernigan

Thanks for your message - I'm happy to assist you.

The error message means that the serial number you are trying to activate is for a different version of Nitro PDF Pro.

Your serial number is for Nitro PDF Pro 13, please uninstall the version you installed.
And then get the correct version 13  installer from the page below:

After installation, activate with your serial number.

Please let me know how that goes.
