Updated Windows, Now License Does Not Work

Recommended Posts

Hi, I just updated my Windows operating system and now my serial number does not work with Nitro Pro. I receive an error message "You have reached the maximum number of installations allowed for this license. This license has only been used on one computer, which I'm currently using. Any help would be appreciated. I purchased a license on 2/6/2021 with email address: eric@s*********js.com and serial number ends in: ****7308

Thank you!

Eric Cone

Greetings @Eric Cone

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

An adjustment has been made on your Nitro PDF Pro license so you could proceed with the activation.
Please try to reactivate by navigating to the Help tab > About Nitro Pro > Activate. Enter the serial number then click Activate. 

Kind regards,
