I have the Nitro Pro 13 installed and for some reason it's not recognizing my activation now.

I uninstalled and reinstalled and I was told that I needed to turn off the firewall in order to get the pre-generated certificate.  So, I turned off my firewall and still the pre-generated certificated does not show.

Please help!

Hello @Cindy Vivar,

Thank you for reaching out to us through our Community Forums and our sincere apologies for this inconvenience.

Based on the information you have provided, you were offered to manually activate the program after clicking Activate button and it is not generating the activation certificate.

We have received similar reports from a few users where the program is not detecting the machine's Internet connection that caused it to not generate activation certificate and to further assist you in addressing this rare behavior, kindly follow these steps:

1. Clear the content of the directory under C:\users\your_username\Appdata\local\temp. For whatever reason, not all temp files automatically remove themselves and is NOT usually caused by Nitro Pro files. Kindly note Appdata folder is hidden and to unhide it, please refer to this article  https://cybertext.wordpress.com/2012/05/29/cant-see-the-appdata-folder/

2. Download and run our Clean Up utility to delete traces of previous Nitro Pro installations:  http://install.nitropdf.com/professional_13400811/install-cleanup/install-cleanup.zip

3. 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.

4. Download and install Nitro Pro 13.38 using below offline installers:

x32 http://install.nitropdf.com/professional_13381739/en/retail/nitro_pro13_ba_x86.msi
x64 http://install.nitropdf.com/professional_13381739/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

5. After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activate by entering your serial number 50499x-xxxxxx-578723

Thank you very much in advance and I am looking forward to hearing back from you.
