22:Error Wrong License number

[Oscar Ramirez]

I can't download Nitro Pro 11 on my Laptop.  It gives me the error message that I have the wrong license number.   I just received the product today and it does recognize the serial number and that I have 2 available downloads.   I am available to use it but it says I'm on a trial basis and also that it is Nitro 9 and I bought Nitro 11.

Hello @oscar,

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

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 11. We then activate it using your serial number. Kindly follow these steps:

1. Uninstall Nitro Pro from your computer then reboot the machine.
2. Download your Nitro Pro from these link/s:
64-bit http://install.nitropdf.com/professional_1107425/en/burn/nitro_pro11_ba_x64.msi
32-bit http://install.nitropdf.com/professional_1107425/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: http://kb.gonitro.com/knowledgebase#/search/64/000001874

3. After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activation and entering your Nitro Pro 11 serial number.

I hope this helps!

Thank you.  It works like a charm.  Clear directions and I was able to confirm that Nitro Pro 11 was installed.  Thank you again.
