Re-installing Nitro Pro 11 after MS Office update

[Kristel Vdv]

Hi

Since a few weeks (after and update of MS Office), my Nitro Pro license has reverted to trial mode and I'm unable to re-activate it. I've tried a lot of things. I've even uninstalled Nitro Pro and re-installed it. But it says that my serial number does not exist. I've also de-activated the license (https://licenses.gonitro.com/prd/portal) but still it does not want to reactive.

Can you please help!

Thanks

Hello @Kristel Vdv,

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

In order to further assist you, could you please provide a screenshot of your 'About Nitro Pro' window under Help tab? This window should show the exact build of the program (format is 13.X.X.X, e.g. 13.2.3.26). 

Lastly, please provide the serial number you have entered that resulted to an error message.

Hello @robertmear,

Thank you for reaching out to us through our Community Forums and for sending those PDF files via 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 using these offline link/s:

x32 http://install.nitropdf.com/professional_13302587/en/retail/nitro_pro13_ba_x86.msi 
x64 http://install.nitropdf.com/professional_13302587/en/retail/nitro_pro13_ba_x64.msi

To know if you have 32-bit or 64-bit, please refer to this article:
https://support.microsoft.com/en-ph/help/15056/windows-32-64-bit-faq 

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.
