Hello @Nilesh,

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

In order to further assist you, 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 and its serial number (format is 12.X.X.X, e.g. 12.0.0.112). 

Lastly, please also provide the serial number of your Nitro Pro 12.

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

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

Sir Waiting for your reply. I removed the Old Nitro version 12 from my PC and tried to reinstall it from the link below

Nitro Product Updates | Download Recent Nitro Pro Releases (gonitro.com)

But I was not able to install it. It just failed to install

 

Kind Regards

Hello @Nilesh,

Thank you for your patience.

To further assist you, let us ensure you have the correct Nitro Pro 12 installers so please refer to these steps:

1. Open your Nitro Pro and log out from your Nitro Sign by clicking the drop-down arrow and selecting Logout. This should be below the 'X' Close button of your program.

2. 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/ 

3. Download and run our Clean Up utility to uninstall your Nitro Pro:  http://install.nitropdf.com/professional_13381739/install-cleanup/install-cleanup.zip

4. 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.

5. Download and install Nitro Pro 12.16.9 using below offline installers:

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:  https://support.microsoft.com/en-ph/help/15056/windows-32-64-bit-faq 

6. After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activate by entering your serial number

7. Reset your Nitro Sign password, login back to Nitro Sign by clicking 'Log In' button.

If the error re-occurs after few days, please let me know so we can check our resources.

Thank you for choosing Nitro and I hope this helps.

Hi 

Your Link to install cleanup does not work. I had a previous download of Nitro Pro 12.16.6.574. I was able to install this one. Now When ever I start Nitro Pro it gives me an error 401. I was able to activate this old version.

Your links to install Nitro PDF in point 5 also do not work.

Kind Regards

Hello @Nilesh,

Our sincere apologies for the inconvenience, however, we have upgraded our servers and has shutdown the one your older version of Nitro Pro runs on so.

Could you please copy and paste the URL for Nitro Pro 12.16.9.574 to a new tab of your web browser? Did it prompt you to save the package?

If yes, please proceed with the rest of the steps above and let me know it goes.

Thank you for choosing Nitro and stay safe always!

Hi AllainU

error 401 has again started. Why is that happening?
