Reinstalling v12 on same PC

[Daniel Rasch]

Hello, I had to reset Windows. I deactivated Nitro Pro before resetting Windows. Now when I'm reinstalling Nitro Pro v12, the activation assistant says "-24: Activation Error". Nitro's website says that zero activations are used.

Also, I'm having trouble changing my e-mail address. I click "change e-mail address" and nothing happens.

Thank you for reaching out through our Community Forums!

Could you please provide your Nitro PDF Pro serial number so we can check its status and records? 

Regarding the change of email address, I believe that you are referring to your Nitro Sign account that is currently associated with the email address d**********h@sanhuausa.com. 
If this is correct, what will be the new email address? 

Kind regards,

I apologize if I have missed your update to this post. 

In checking the provided serial number, I can see that it is a version 12 license. 
Please note that we no longer support Nitro Pro 12 and older versions as these versions have reached the End of Life (see Sunset Policy) and their activation servers have been shut down. 

To upgrade to the latest version with a discounted price, please visit our Upgrade page at https://www.gonitro.com/support/upgrade 

We recommend upgrading to our latest version, Nitro PDF Pro 14, which comes with significant stability and security improvements and many feature enhancements, particularly in Conversion, OCR, and Accessibility functions. 

Regarding the change of email address on your Nitro Sign account, please refer to the link below
