Activation Problems

[OTC Cloud]

I received an email with the serial numbers on it but once I put the serial number in the activation code it says the serial number entered does not exist.  

I have tried it numerous ways and they all come out the same way.  Could really use some help. Thank you

Hello @OTC Cloud,

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 12.X.X.X, e.g. 12.0.0.112). 

Lastly, could you please provide the serial numbers of your Nitro Pro?

To send it 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 @OTC Cloud,

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_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:

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.
