Nitro Pro 12 will not activate (-24 Activation Error)

[Jason Marino]

Hello I am installing Nitro Pro 12 on my new computer with my license which has no active activations, as confirmed via the license lookup link, and when I input the serial number it gives me an error message. There is no reason the serial number should not work, I have deactivated it from all other computers and confirmed this via the web page.

Hello @Jason Marino

Thank you for your message - I can help you out.

We have upgraded our activation servers. Please install the latest Nitro Pro 12 update (12.16.9.574) so you can reactivate successfully:

Then activate with your Nitro Pro 12 serial number.

I hope this helps!

Hello,

I cannot activate Nitro Pro 12 with offline installer. 

I tried installing online version from your link https://www.gonitro.com/nps/product-details/downloads and I am getting Nitro Pro Setup Wizard Has Failed.
