Activation won't work for Version 12

[Kenneth Rushton]

I have version 12 and can't get it to activate using my serial #. I'm now working with the trial version, but would like to activate it. The website shows 0 activations and 2 remaining. Activating I get error 24.

Hi @Kenneth Rushton

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

Please check which version of Nitro PDF Pro is installed on your machine, this can be located under the Help tab > About Nitro Pro. 
If the version is not Nitro Pro 12.16.9.574, please uninstall then install that version by downloading the installer from the following location: 

https://www.gonitro.com/nps/product-details/downloads - Click the 'Download Nitro Pro 12' link  

Once installed, you should be able to activate it using your version 12 license. 
To activate, go to the Help tab > About Nitro Pro > Activate. Enter the serial number then click the Activate button. 

 

Kind regards,

[Kenneth Rushton]

I tried the link, but after after activating got a failed message that "Nitro Pro Setup Wizard has failed". I had previously installed version 12, but the activation kept asking for a certificate. I even uninstalled version 12 and tried the download link and still get the same message.

Hi @Kenneth Rushton

Please try installing Nitro PDF Pro 12.16.9.574 using the MSI offline installer. Here's the link to the installer:

32bit - http://install.nitropdf.com/professional_12169574/en/retail/nitro_pro12_ba_x86.msi 
64bit - http://install.nitropdf.com/professional_12169574/en/retail/nitro_pro12_ba_x64.msi

Please let me know how the installation works for you.
