I recently purchased a new computer and I am unable to locate the email with my serial number so that I can activate my license on this computer. I am unable to boot up old computer so that I can deactivate my license from there. Any suggestions on how I can get my serial number so that I can use this program on my new computer?

Hello @Morgan Tau,

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

I am afraid I am unable to find a purchase under your name or email address.

In order to help you with your request, could you please provide the following information for me?

-The full name and address of the purchaser
-The email address used to purchase Nitro Pro.
 

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 @Morgan Tau,

Thank you for the private message.

Please be informed that '-20: Error - Invalid License Number' 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 13. 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 13.33 using these offline link/s:

x32 http://install.nitropdf.com/professional_13332645/en/retail/nitro_pro13_ba_x86.msi
x64 http://install.nitropdf.com/professional_13332645/en/retail/nitro_pro13_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.
