Error when opening Nitro Pro 12

[Richard Poole]

I receive an error every time I go to launch my Nitro 12 Pro software:

This happens regardless of whether I launch Nitro 12 Pro by it's shortcut or by opening a PDF. I have tried to uninstall/reinstall Nitro Pro 12 and have reactivated it.

It says to contact support, but it seems like you have to be Nitro VIP in order to be able to do so.

Anyone have any thoughts? This is quite annoying.

Hi @Richard Poole,

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

Please open your Nitro Pro installation then close the 401 error message if it shows up. At the top right, click logout then login again using your Nitro Sign account. 
After these steps, please observe if you still get the same error message.

Kind regards,

Hi,

Unfortunately the error still occurs after logging out and back in.

Thanks,

Richard

Hi @Richard Poole,

Could you please check which specific build of Nitro Pro 12 is installed on your computer? This can be located under the Help tab > About Nitro Pro (ex: Nitro Pro 12.x.x.x)

Kind regards,

Hi Reymund, I'm using Nitro Pro 12.0.0.108:

Hi @Richard Poole,

My apologies for the inconvenience.
I recommend updating your Nitro Pro 12 installation to the latest build which is 12.16. You can download the Nitro Pro 12.16 from the following location: 

https://www.gonitro.com/nps/product-details/downloads - Click the 'Download Nitro Pro 12' link.  

To do the update, simply run the .exe and it will automatically update your installation to Nitro Pro 12.16. 
After the update, try to logout (located at the top right of Nitro Pro) then log back in using your Nitro Sign account.

Kind regards,

Hi @Reymund G.,

Thank you - after the upgrade and logging out and back in, the error seems to have gone away. I'll keep an eye on it for the next little while and report back if it comes back.

Appreciate the help.
