Hello @Kim Martin,

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

As part of troubleshooting, please uninstall the program, reboot the machine then reinstall using the below MSI 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 

After installation, you can activate it by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activate by entering your serial number 234600-xxyyzz-170034

When done, open a browser, visit https://cloud.gonitro.com/, reset your password, open again Nitro Pro 12, click the 'Log in' link at the top-right, and enter your username and password to login into your Nitro Sign account. 

Thank you for your patience and please let us know how it goes on your end.

I did everything as instructed.  Still getting Error 401.  The document opens but not before giving me the error message.

Your msi file does not download. Nitopro's support sucks.

Hello @walktall777@gmail.com,

Thank you for reaching out to us through our Community Forums and our sincere apologies for your frustrations.

If you are using Chrome or any of the Chromium-based browsers (e.g., Vivaldi, etc.) and you are unable to access the above installer links, you're more than likely experiencing the results of a new security feature that was silently pushed out to the browsers, which blocks .exe/.msi/etc downloads without any visible error or prompt on the browser's frontend user space. In order to bypass this, please try these steps:

a. Right-click the link you're trying to download, and select "Save link as..."
b. Choose your save location and select "Save"
c. On the bottom edge of your browser window, the Downloads bar should now appear and the file will show up with a red error icon, attempting to block the download. Press the caret button and select "Keep"

Thank you for your patience and please let us know how it goes on your end.
