Nitro deactivated and can't get it re-activated

[rebeblack]

I had a windows 10 update that knocked out my Nitro program.  The first time I tried to open a pdf after the update, I could not find Nitropro in my system.  It somehow deleted from my computer.  So, I went and re-downloaded and when I put my serial number in for activation, it said it did not exist.  I tried following the help steps and deactivating online and tried again and still it says it did not exist.

Hello @rebeblack,

Thank you for the private message.

Looks like we need to uninstall the current version of Nitro Pro on your computer and install Nitro Pro 12. 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 12.16 using these offline link/s:

x32 http://install.nitropdf.com/professional_12163574/en/retail/nitro_pro12_ba_x86.msi 
x64 http://install.nitropdf.com/professional_12163574/en/retail/nitro_pro12_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!

Thank you Allain.   I searched and searched the Nitro Pro website for the version 12 to download when I first lost it.  Thank you so much for posting the links.  Downloading Version 12 again worked and it automatically activated!   Now, I kept the install file on my computer should the next Windows update knock out NitroPro again.
