Changed laptop, previous serial number won't activate on new laptop newer version

[David Hertwig]

From a previous thread, maybe it's due to my serial number being with an older version of the installation on my old laptop.  How can I securely send my serial # so you can correct it to activate on my new laptop?  My current download on my new laptop is version 13.58.0.1180.  Thanks.

Hello @David Hertwig

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

I checked your serial number. It is a Nitro Pro 10 serial number. Please note that we no longer support Nitro Pro 10 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:
