Hello @Saju Chacko,

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

Before continuing, please be aware that Nitro Pro 11 or older are already discontinued as documented in our Sunset Policy: https://www.gonitro.com/support/sunset-policy . With that, support for the discontinued versions are no longer available.  

If you are interested in upgrading your license to Nitro Pro 13, kindly access our Upgrade Portal and enter your Nitro Pro 10 serial number: https://www.gonitro.com/pro/upgrade 

You may also want to purchase Nitro VIP Access (formerly Software Assurance) that entitles users to free upgrades for the next release of Nitro Pro and Premium Support for one year after the purchase date. (Premium Support is prioritized ticket support with our Technical Support staff/Nitro Customer Success and Service Team for one year after the purchase date).

You should then receive an email confirmation with a new serial number to activate Nitro Pro 13 and to know more about some enhancements and fixes with Nitro Pro 13, please visit our Release Notes page https://www.gonitro.com/nps/product-details/release-notes 

Please be aware that the issue of license reverting to 'Trial Expired' when a major Windows Updates was installed and generating null-id (Computer ID of all '0's) has been fixed in version 13. In addition to that and many other feature improvements, version 13 also contains some important security vulnerabilities fixes that you might want to consider when deciding whether to upgrade to it or not. You can find out more about these fixes here:  https://www.gonitro.com/nps/security/updates 

However if you prefer working with an older version and as a courtesy, I just made an adjustment on your license, so you can now activate your copy of Nitro Pro by going to Help tab > About Nitro Pro > Activate, entering your serial number and clicking Activate.

Thank you for choosing Nitro and I hope this helps!

Hello @sammy hightower,

Thank you for the private message.

On the machine you're having issue activating, I just made an adjustment on your license, so you can now activate your copy of Nitro Pro by going to Help tab > About Nitro Pro > Activate, entering your serial number and clicking Activate.

Our record shows you are experiencing an issue activating the license is because the computer that the software was installed on did not generate a proper Computer ID (which is a Nitro-specific ID, which generates a unique Computer ID for each computer that the software is installed on). Instead, a Computer ID of all '0's was generated.

Thank you for choosing Nitro and I hope this helps!
