Error -20 when activating newly purchased license

[Brandon V 0]

Hi,

We purchased a license yesterday and upon activating it today we received a -20 error code. I attempted to reset the license in the activation portal and it gave me a invalid serial message. 

 

Thanks,

Brandon

Hello @Brandon V,

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

In order for me to further assist you with your concern, could you please provide the following?:
-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'. 
-Nitro Pro build (format is 13.X.X.X, e.g. 13.2.2.25) you are working with. You can find this out by clicking on 'About Nitro Pro' under the Help tab or you can go to Control Panel > Programs and Features.

Thank you very much in advance and I am looking forward to hearing back from you.

Hello @Brandon V,

Thank you for this information.

Please be informed that '-22 Error Wrong 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 using these offline link/s:

x32 http://install.nitropdf.com/professional_132626/en/retail/nitro_pro13_ba_x86.msi 
x64 http://install.nitropdf.com/professional_132626/en/retail/nitro_pro13_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!
