Hello @AMOIR JAHANGIRI,

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 & 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:

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.

how often do you shut down your server for older versions? I have the right to use the product that comes with that serial number & I don't remember anyone telling me that the serial number is for a limited time.
