Thanks for reaching out to us!

Please get the latest version 13 installer 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 this helps. Let me know if you require anything else.

Hello @Leslie V

I did it and I get this error. "The serial number entered does not exist. Click 'back' and make sure that you have entered the serial number correctly. If you still encounter problems, please contact support via the link below: ...'.

As i said i had a computer in which we had bought nitro 9. In March we upgrade it, by paying an amount to nitro 13, but wasn't given us any serial number because the upgrade was automatic.

Can you give me the serial number via message or email ?  We have the invoice or anything you need.

Thank you for your response and i'm waiting for your help.
