Serial number is active but will not activate on my computer.... PLEASE HELP

[Marissa Fontaine]

I have the latest version.  Nitro was licensed and working on my computer.  We moved offices, I'm on the same computer but now Nitro has me under a "trial version" that has since expired.  My serial number won't active.  I followed the activation assistant and got the error "invalid license."   I can send you my serial number privately for you verify.   Am stuck not able to work without Nitro!

Hello @Marissa Fontaine,

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

In order to further assist you, could you please provide a screenshot of your 'About Nitro Pro' window under Help tab? This window should show the exact build of the program (format is 13.XX.X.XXX, e.g. 13.46.0.937). The same information is available by going to Control Panel > Programs and Features.

Lastly, please provide the serial number of your Nitro Pro. This matters because our business installers are different from the online ones.

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

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

Hello @Marissa Fontaine,

Thank you for the private message.

Please note that we no longer support Nitro Pro 11 and its activation servers have been shut down. Additionally, you have installed Nitro PDF Pro 13 which is why it is not accepting your serial number

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.  

Download and run our Clean Up utility to uninstall your current Nitro Pro and reboot your machine: 

http://install.nitropdf.com/professional_12169574/install-cleanup/install-cleanup.zip 

Then clear all your Downloads folder or delete all downloaded Nitro installers. This step is important because we noticed that if you are saving all the installers and you download them in the same folder (like the downloads folder), the EXE can pick up any MSI installer in that folder and you may pick-up one of the older builds instead of the newly downloaded package.

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-931974:
https://www.gonitro.com/nps/product-details/downloads 

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:
https://support.microsoft.com/en-ph/help/15056/windows-32-64-bit-faq 

Important: If you are using Chrome or any of the Chromium-based browsers (e.g., Vivaldi, etc.) and you are unable to access the above installer links, you're more than likely experiencing the results of a new security feature that was silently pushed out to the browsers, which blocks .exe/.msi/etc downloads without any visible error or prompt on the browser's frontend user space. In order to bypass this, please try these steps:

a. Right-click the link you're trying to download, and select "Save link as..."
b. Choose your save location and select "Save"
c. On the bottom edge of your browser window, the Downloads bar should now appear and the file will show up with a red error icon, attempting to block the download. Press the caret button and select "Keep"

Thank you for choosing Nitro and I hope this helps.
