Activation on New Device

[Jacob Schultz 0]

I have been using Nitro Pro for many years and love the program. I recently got a new desktop and tried to activate my Nitro Pro on this device but I keep getting an error when entering the serial number during activation. Error message states the following,

"The serial number entered does not exist. Click 'Back' and make sure that you have entered the serial number correctly. If you are still encountering problems, please contact support via the link below: Submit a support request". 

I logged into my Nitro account online to ensure I do have the correct serial number and also confirmed I still have 1 out of 2 activations available through Nitro. Still, the serial didn't work. I followed the other suggestions provided by Nitro Support to deactivate all accounts then reactivate them, but now neither device is working with Nitro Pro. I tried uninstalling Nitro PDF and reinstalling it, but that didn't work either. 

I run need this working ASAP... Please help me!!

Hello @Jacob Schultz,

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

In order 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 @Jacob Schultz,

Thank you for the private message.

Please be informed that 'The serial number entered does not exist' means the serial number you are trying to activate is for a different version of Nitro Pro. Looks like we need to uninstall the current version of Nitro Pro on your computer and install Nitro Pro 12. We then activate it using your serial number. Kindly follow these steps:
 
1. Uninstall Nitro Pro from your computer by going to Control Panel > Programs > Programs and Features then reboot the machine.

2. Please 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.

3. Download your Nitro Pro 12 using these offline link/s:

x32 http://install.nitropdf.com/professional_12163574/en/retail/nitro_pro12_ba_x86.msi 
x64 http://install.nitropdf.com/professional_12163574/en/retail/nitro_pro12_ba_x64.msi

If you are unsure if your machine is using 32 or 64-bit, please refer to this link: https://kb.gonitro.com/knowledgebase/#/search/64/000003790 

4. After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activation and entering your serial number.

Thank you for choosing Nitro and I hope this helps!
