Activation of Nitro 11 following computer change

[Peter Campbell]

I have recently changed computers.  I am running Nitro Pro 11.  I am aware that it is no longer supported.

It was working fine on the old computer.  The de-activation/reactivation process is simply impossible - it just doesn't work, sending me round and round in circles. 

Would someone please guide me as to how to achieve this.  It shouldn't be this hard.  Would you like to know my serial number?

Greetings @Peter Campbell

Thank you for reaching out to us through our Community Forums!

Aside from no longer being supported, the activation servers of Nitro Pro 11 and older have been shutdown which is why you are having issues with the activation or deactivation. 
However, old licenses were transferred to the new activation server and will now work with the latest build of Nitro Pro 12 which is 12.16.9.574.

You can find the latest Nitro Pro 12.16.9.574 here: 
https://www.gonitro.com/product-details/downloads - click the 'Download Nitro Pro 12' link. 

Once Nitro PDF Pro 12 is installed, you can activate it by going to the Help tab > About Nitro Pro > Activate. Enter the serial number then click Activate.  

We recommend upgrading to our latest version, Nitro PDF Pro 13, which comes with significant stability and security improvements, as well as many feature enhancements, in particular in conversion and OCR functions. 
If you are interested to upgrade your existing license to version 13 with a discounted price, please visit our Upgrade page at https://www.gonitro.com/support/upgrade

Kind regards,
