Activate Nitro Pro 11 after change from Win 8.1 to Win 7 Pro

[Mark White]

I cannot activate Nitro Pro 11 after changing computers. It was on Win 8.1 and now is on Win 7 Pro

I've used all the ways available to me.
From the program all is well until you click on the web address. It says server not found.

Go on the website and enter serial number. You get to Deactivate Page.
Click on deactivate and you get a message telling you to choose a device.
But there is no option to choose device on screen.

I have tried countless times and I would like to have someone tell me exactly what to do.

Thanks

Hello @Mark White,

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

Please note that we no longer support Nitro Pro 11 and its activation servers have been shut down which is why you are having issues activating. 

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, 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 serial number 234600-xxxxxx-278724:

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:

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.
