Problem with activation

[Alicia Doyle 0]

I have had Nitro for many year, but I had a computer issue and lost almost everything.  I am trying to reactivate the program and it says the serial number is invalid.  I deactivated it and tried it again and I am still having the same issue.

Hello @Alicia Doyle,

Thanks for the private messages.

Before continuing, please be aware that Nitro Pro 11 or older are already discontinued as documented in our Sunset Policy: https://www.gonitro.com/support/sunset-policy . With that, support for the discontinued versions are no longer available.  

If you are interested in upgrading your license to Nitro Pro 13 with a discounted rate, kindly access our Upgrade Portal and enter your Nitro Pro 10 serial number: https://www.gonitro.com/pro/upgrade 

You may also want to purchase Nitro VIP Access (formerly Software Assurance) that entitles users to free upgrades for the next release of Nitro Pro and Premium Support for one year after the purchase date. (Premium Support is prioritized ticket support with our Technical Support staff/Nitro Customer Success and Service Team for one year after the purchase date).

You should then receive an email confirmation with a new serial number to activate Nitro Pro 13 and to know more about some enhancements and fixes with Nitro Pro 13, please visit our Release Notes page https://www.gonitro.com/nps/product-details/release-notes 

 

However if you prefer working with an older version and as a courtesy, please be informed that '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 10. 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 10 using these offline link/s:

x64 http://install.nitropdf.com/professional_105914/en/burn/nitro_pro10_ba_x64.msi 
x32 http://install.nitropdf.com/professional_105914/en/burn/nitro_pro10_ba_x86.msi

If you are not sure which to pick, this will help: https://kb.gonitro.com/knowledgebase#/search/64/000003790

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

Thank you for choosing Nitro and I hope this helps.
