I was having trouble deactivating to move PDF Pro to a new computer, and then bought the upgrade to 13.  However when I install PDF Pro 13 I get the message that it is still looking for a deactivation certificate when trying to activate 13.  My serial number shows no active users so there is no one to deactivate.  Going in circles.

Hello @allen haugrud,

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

A program that is asking for a deactivation certificate commonly happen when an old build is installed.

To further assist you, let us ensure you have the latest build installed by referring to these steps:

1. Download and run our Clean Up utility to uninstall your current Nitro Pro and reboot your machine:

http://install.nitropdf.com/professional_13.53.3.1073/install-cleanup/install-cleanup.zip

2. 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 and install Nitro PDF Pro 13.53 using the installer from this page:
https://www.gonitro.com/nps/product-details/downloads 

If you are getting the 'Nitro Pro Wizard has failed' message using our .exe package, it is because it requires a stable Internet connection to download installation files so please use offline English MSI packages:

x32 https://downloads.gonitro.com/professional_13.53.3.1073/en/retail/nitro_pro13_ba_x86.msi 
x64 https://downloads.gonitro.com/professional_13.53.3.1073/en/retail/nitro_pro13_ba_x64.msi

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

Important: If you are using Chrome or any of the Chromium-based browsers (e.g., Vivaldi, etc.) and you are unable to access the above installer links, you're more than likely experiencing the results of a new security feature that was silently pushed out to the browsers, which blocks .exe/.msi/etc downloads without any visible error or prompt on the browser's frontend user space. In order to bypass this, please try these steps:

a. Right-click the link you're trying to download, and select "Save link as..."
b. Choose your save location and select "Save"
c. On the bottom edge of your browser window, the Downloads bar should now appear and the file will show up with a red error icon, attempting to block the download. Press the caret button and select "Keep"

4. After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activate by entering your serial number 5049xx-xxxxxx-814200

Thank you for choosing Nitro and I hope this helps.
