Serial Number Activation Error

[kneilccg]

We are trying to activate our serial number on a new PC that has the updated NitroPro13. We have deactivated the serial number from the old PC that has NitroPro11, but are receiving an error message saying the serial number does not exist.

Hello @kneilccg,

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

Kindly note we are unable to pull-up your serial number using your email address so in order for me to further assist you with your concern, could you please provide the following?:

-The serial number of your Nitro Pro. This matters because our business installers are different from the online ones.
-Build of Nitro Pro are you working with? You can find this out by clicking on 'About Nitro Pro' under the Help tab (format is 13.X.X.X, e.g. 13.2.3.26) or you can go to Control Panel > Programs and Features.
-A screen shot of the error message you are receiving and/or any important information. To find out how to take a screen shot, check out this link: https://kb.gonitro.com/knowledgebase/#/search/screen/000004108 

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 @kneilccg,

Thank you for your 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 11. 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 11 using these offline link/s:

x64-bit: http://install.nitropdf.com/professional_1108470/en/burn/nitro_pro11_ba_x64.msi 
x32-bit: http://install.nitropdf.com/professional_1108470/en/burn/nitro_pro11_ba_x86.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!
