Cannot Deactivate NitroPro 10.5.6.14 on WIndows 10

[Greg Merrick]

I just get a -24 error when I try to deactivate in order to move to a new PC.

When I tried to create a ticket it said my serial number was for version 12 and has 0 activations.  Why is this deactivation/activation process so difficult?

Hello @Greg Merrick

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

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:

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 10 serial number.
