I have a Nitro Pro 12 license but it won't let me do a second install or activation.

I have already tried uninstalling with the uninstall tool. After rebooting, I am unable to install Nitro Pro 12 as it keeps saying the installation failed.

Hello @Jonathan Hwang,

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

I believe you are installing using our .exe which is our online installer and in order to further assist you, please refer to these steps:

1. 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.

2. You can find Nitro Pro 12 offline installer links below:

x32 http://install.nitropdf.com/professional_12169574/en/retail/nitro_pro12_ba_x86.msi
x64 http://install.nitropdf.com/professional_12169574/en/retail/nitro_pro12_ba_x64.msi

To know if you have 32-bit or 64-bit, please refer to this article:

5. After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activate by entering your serial number 234600-xxxxxx-308020

Thank you for choosing Nitro and I hope this helps.
