WHEN ACTIVATING THE SERIAL NUMBER IT DOES NOT WORK

[SANDRAV]

I had to download the NITROPRO again because it did not work so I used instructions from one of the conversations hereto. I deleted the program and installed it again and now when I ask to activate it it says that the license number does not exists. Please help

Hello @SANDRAV,

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

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!
