Activation Problem on Replacement Computer

[Orville Norton]

I am trying to activate Nitro Pro on my new replacement computer.  When I enter the serial number in the software, I get the message that it is not valid.   I tried to submit a support ticket, it has me to enter the serial, instructs me to deactivate, then a box pops up saying to show what device to deactivate from.   But, there are not choices for devices.   After I click deactivate, I try to enter the serial again and it still says not an existing number.   The serial starts with 234602.  I get in a loop and was unable to submit a support ticket.   Please help.  Thank you.

Hello @Orville Norton

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

You a version 9 serial number. Please note that we no longer support Nitro Pro 9 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 9 serial number.
