Error 23 - Unable to re-activate license after Windows update

Recommended Posts

A recent windows update seems to have changed something, and my copy of Nitro Pro 10 no longer works. I have deactivated the license in the portal and confirmed that there are NO active installations for my license key. However, I'm still getting Error 23 saying my license key has already been used. I've restarted the program and have attempted re-activation multiple times, same results.

Please let me know what steps I must take to get this working again ASAP.

Hello @Steve King,

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

Kindly note upon the upgrade of the operating system or installing a major Microsoft update, the Computer ID is changed, as it is comprised partially by the operating system. Once changed, this will no longer recognize the original installation causing the program to revert to trial mode.

Since I am unable to pull-up your account, could you please provide the serial number of your Nitro Pro 10?

To send it 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 @Steve King,

Thank you for the private message.

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 with VIP Access (formerly Software Assurance), kindly access our Upgrade Portal and enter your Nitro Pro 10 serial number: https://www.gonitro.com/pro/upgrade 

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' 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 build, 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!
