Help with serial number activation on new computer

[Ana-Lina Vrbancic]

Hi, I just bought a new computer as the old one did not work property anymore. HOwever, I have problems installing my NitroPro.

I tried by de-activating the serial number and it says I have now 2 activations left. However, when I try to active again, it comes up with the following messae:

The serial number entered does not exist. Click "Back" and make sure that you have entered the serial number correctly.

If you still encounter problems, please contact support via the link below.

However, this link takes me to Submit a ticket, which just gives me the same instructions.

What do I do to get this activated on my new computer? Thank you.

Hello @Ana-Lina Vrbancic

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 what you have and get the correct version 13 installer from the page below:

After installation, activate with your serial number.

Please let me know how that goes.
