Deactivating Nitro

[FYZICAL MetroWest]

I am trying to deactivate Nitro Pro on one computer so I can install it on my new computer. When I click deactivate in Nitro Pro, I get the -24: Activation Error notice. I went onto https://www.gonitro.com/support/ticket as instructed by the Nitro help pages, but when I enter the info for the support ticket, it brings me to the Licensing portal. I click deactivate there, and am told to "choose a device." The page states that if the licensing portal doesn't solve the problem, submit a support ticket, but that link just brings me back to the licensing portal - round and round.

Greetings @FYZICAL MetroWest

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

Using the license portal, please check the version of your serial number. If the version is 12, please install Nitro PDF Pro 12.16.9.574 so you could successfully activate. The Nitro PDF Pro 12.16.9.574 installer can be located from the link below:

https://www.gonitro.com/product-details/downloads - click the 'Download Nitro Pro 12' link. 

If the version is 13, install Nitro PDF Pro 13 by clicking the 'Download Nitro Pro 13' from the above link. 

Kind regards,

I'm not trying to download, I'm trying to deactivate my license so I can move it to another computer.

Hi @FYZICAL MetroWest

Hi @Michael Tims

Deactivation on old installations will no longer work since old serial numbers were moved/migrated to the new activation server. Along with the migration, old serial numbers were reset and enabled to activate the latest build of Nitro PDF Pro 12. This means, you do not need to deactivate the old installation (since it will no longer reach the old activation server) and simply install the latest build of Nitro PDF Pro 12 on the new computer. 

The Nitro PDF Pro 12.16.9.574 installer can be located from the link below:

https://www.gonitro.com/product-details/downloads - click the 'Download Nitro Pro 12' link. 

Once Nitro PDF Pro 12.16.9.574 is installed, proceed with activating it using your existing serial number.

Kind regards,

The serial numbers I have are:

234601-xxyyzz-948734

234601-xxyyzz-855168

234601-xxyyzz-502902

234601-xxyyzz-345794

234601-xxyyzz-775709

It's fine to deactivate all of them; as long as they are all deactivated I can reactive them on the right computers.

Hi @FYZICAL MetroWest

Those serial numbers are good for activation and does not need any deactivation. 
To successfully use these serial numbers, please install the latest build of Nitro PDF Pro 12 (12.16.6.574). The installer can be located from the link below:

https://www.gonitro.com/product-details/downloads - click the 'Download Nitro Pro 12' link.

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

Kind regards,
