Deactivation not possible in the Activation Portal

[TScaff]

Hello, I am having the exact same issue, where I go to deactivate a licence and an error pops up and says  "Please select devices to deactivate" and nothing happens.
Can i PM my serial number privately?

Hello @TScaff,

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

We want to make you aware of the change to your product that may affect its activation performance and to further assist you, could you please provide the serial number of your Nitro Pro?

To send it via private message, hover your mouse on top of my name 'AllainU' and select 'Message'.

This matters because our business installers are different from the online ones.

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

Hello @TScaff,

Thank you for the private messages:

Please note that we no longer support Nitro Pro 11 and its activation servers have been shut down and in regard to our Activation Portal, there is no need to deactivate if there is nothing to release.

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 have stopped making feature enhancements to version 12 once we released version 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-xxxxxx-734713:

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.
