-20: Error - Invalid License Number

[GTRider87]

I purchased Nitro Pro yesterday, and was given serial number ********************* in my confirming email.  When I tried to activate it in Nitro Pro, I received the “-20: Error - Invalid License Number” message.  I tried the online activation portal and received the message, “Please enter a valid serial number.”

I read AllainU’s response Friday to a similar question, so I followed his instructions of removing the Nitro Pro 11 trial version and installing Nitro Pro 12.  But is still received the “-20: Error…” message.

What should I do now?

Hello Chris,

Thanks for reaching out to us!

Please uninstall the old version of Nitro Pro and install Nitro Pro 13. You can get the correct version 13 installers from this page: 
https://www.gonitro.com/nps/product-details/downloads

After installation, you can activate by opening Nitro, click on the Help tab > About Nitro Pro > Activate and enter your serial number.

I hope that helps!
