Deactivating is not working (need it to switch to new PC)

[Judith Kloibhofer]

Hello,

I have troubles with deactivating my Nitro Pro license, which I need to do to be able to use the license on my new PC. When trying to deactivate it in the application the error states: "-24: Activation Error". I also tried the online option to deactivate within the portal by typing in the serial number. However, then a window pops up which says: "please select devices to deactivate", but my only option is to say ok and I cant select any device somewhere. After pressing ok nothing happens. If needed, I can also send my serial number/licence number - however, don't want to publish it here on the forum.

Please provide the serial number that you will use to activate Nitro PDF Pro on the new PC.
You can post here the serial number as we (moderators) always hides the serial number before approving each post.

Hi @Judith Kloibhofer

In checking your serial number, I can see that it was a version 10 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 are 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,
