Nitro Pro not deactivated

[Monika Diehm]

When changing PC, this Nitro Pro license is shown as activated ("Find license)  although it has been deactivated on the old PC and no serial number is displayed here.

When clicking "Deactivate" the message is shown: "Please select devices to deactivate" but there is no selection.

Without deactivating I cannot activate at the new PC. What can i do?

Hello @Monika Diehm,

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

Looking at our purchasing servers, you have multiple versions of Nitro Pro programs and to further assist you, could you please provide the serial number you are trying to deactivate?

Thank you very much in advance and I am looking forward to hearing back from you.

Hello @Monika Diehm,

Thank you for this information.

Please note that we no longer support Nitro Pro 11 and its activation servers have been shut down which is why its installers are no longer available for download. 

We recommend upgrading to our latest version, Nitro PDF Pro 13, 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 PDF Pro 13 at a discounted rate, please visit our Upgrade page https://www.gonitro.com/pro/upgrade 

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 stopped making feature enhancements to version 12 once we released Nitro PDF Pro 13.  

You can find the Nitro Pro 12.16.9.574 installer on this page and activate it with your current Nitro Pro 11 serial number 234600-xxyyzz-604763:

If you are getting the 'Nitro Pro Wizard has failed' message using our .exe package, it is because it requires a stable Internet connection to download installation files so please use offline English MSI packages instead:

x32 http://install.nitropdf.com/professional_12169574/en/retail/nitro_pro12_ba_x86.msi 
x64 http://install.nitropdf.com/professional_12169574/en/retail/nitro_pro12_ba_x64.msi

To know if you have 32-bit or 64-bit, please refer to this article:

Thank you for choosing Nitro and I hope this helps.
