Reinstallation required after updating to Windows 11

[gegginton@hotmail.co.uk]

My installation of Nitro Pro (11.0.3.173) has reverted back to a trial version.  I am struggling to reactivate it.  I have tried through your website to deactivate it as suggested by the text, but I get an error message saying "Please select devices to deactivate."  There is nowhere on the page to select any device - so I am stuck.  I would be grateful for your assistance.  Thanks.

Hello,

Thanks for reaching out to us! I am happy to assist you.

Please note that we no longer support Nitro Pro 11 and its activation servers have been shut down.

We recommend to upgrade to our latest version, V13, 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 Pro 13, please visit our upgrade page:

Alternatively, you can upgrade to the latest build of Nitro Pro 12. Per our Sunset Policy, https://www.gonitro.com/nps/product-details/sunset-policy, we have stopped making feature enhancements to version 12 once we released version 13. You can find Nitro Pro 12 installer from the page below and activate it with your current Nitro Pro 11serial number.
