Unable to Sign In

Recommended Posts

Have received an email advising to update by end of March. However receive an error message when trying to sign in. Have reset password but still the same problem. Error message: "Unable to connect to the Internet. Please check your connection and try again".

I am contacted to the internet so unsure why the above error message is being displayed.

If any one can assist, that would be greatly appreciated.

Many thanks

Hello @Dean T,

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 10.X.X.X, e.g. 10.5.9.11). 

Lastly, a screenshot of the error message you are receiving. To find out how to take a screen shot using Snipping Tool, check out this link: https://support.microsoft.com/en-us/windows/use-snipping-tool-to-capture-screenshots-00246869-1843-655f-f220-97299b865f6b

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.

Hello @Dean T,

Thank you for the private message.

As a courtesy of being a valuable customer of Nitro, we want to make you aware of an upcoming change to your product that may affect its performance. 

To continue offering our customers the very best PDF tools, we’re upgrading our servers and subsequently shutting down the one your older version of Nitro Pro runs on so please install Nitro Pro 12.16.9.574 using below direct MSI links:

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 

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

Thank you for choosing Nitro and I hope this helps.

Hi, I keep an error 401 when opening Nitro Pro. Sometimes it also displays a message at the top of the screen which says trial has expired.

Please confirm if this was a trial version i installed.

Many thanks
Dean
