The serial number you provided is a version 9 license. Please note that we no longer support Nitro Pro 11 and older and its activation servers have been shut down.
Thus, any activation or deactivation attempt on these versions will no longer work. Also, access to the installer for these versions is no longer available.

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. 
To upgrade to Nitro PDF Pro 13 with a discounted price, please visit our Upgrade page at https://www.gonitro.com/support/upgrade 

Alternatively, you can continue to use your existing serial number by installing the latest build of Nitro PDF Pro 12 which is 12.16.9.574.
Per our Sunset Policy, https://www.gonitro.com/nps/product-details/sunset-policy, we stopped making feature enhancements to version 12 once we released Nitro PDF Pro 13.  

You can find the Nitro Pro 12.16.9.574 installer from the link below and activate it with your current Nitro Pro serial number:
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.  

Kind regards,
