Hi there,

Our company purchased the Nitro Pro Version shortly before Christmas 2020. It was immediately working as it should when I entered our serial number details. Now, after not having used the programm for approx. two weeks, it says that the tasks we would like to perform are only working with the pro version!

How can we solve this problem immediately? What is required from my end for you to assist? The hints we saw from the online help are not working.

Thanks in advance!
Nils

Hello @Nils Liesner,

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

If repairing didn't help, 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)?

To send it via private message, hover your mouse on top of my name 'AllainU' and select 'Message'.

Thank you for choosing Nitro and I hope this helps.

Hello @Nils Liesner,

Thank you for the private message.

In order to fix this issue where the program is not generating activation certificate, please refer to 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 uninstall your Nitro Pro:   http://install.nitropdf.com/professional_13353685/install-cleanup/install-cleanup.zip

NOTE: This clean-up tool will erase any existing signature files within Nitro so please save them to another location before using the clean-up tool in order to keep them. Please see this link for backing up custom stamps/signatures: https://kb.gonitro.com/knowledgebase#/search/stamps/000004307 

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 13.35 using below offline installers:

x32 http://install.nitropdf.com/professional_13353685/en/retail/nitro_pro13_ba_x86.msi
x64 http://install.nitropdf.com/professional_13353685/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

Thank you for choosing Nitro and I hope this helps.
