Can't activate serial on a new computer

Hi there,

We're currently attempting to activate an existing serial on a new PC that we've removed/deactivated from an old PC. Getting the below error:




We believe the software previously on the old pc was Nitro 11 Pro v, we've first tried to activate on the newest Nitro 13, but then uninstalled and attempted on Nitro with the same result.


We're unable to submit a support request as we don't have the VIP level support.

Any assistance would be appreciated.

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

Please note, we no longer support Nitro Pro 11. It has been discontinued as documented in our Sunset Policy: https://www.gonitro.com/nps/product-details/sunset-policy

You can either upgrade to Nitro Pro 13: https://www.gonitro.com/pro/upgrade

Or install the latest Nitro Pro 12 update so you can continue using your purchased license: 

Then activate with your Nitro Pro 11 serial number.

I hope this helps. Let me know if you require anything else.

Hi Leslie,

Now we're getting an error that that version (using nitro_pro12.exe) won't install. Giving me the error "Nitro Pro Setup Wizard has failed"

So I've found the .msi link to this and downloaded the latest version and it seems to have activated.

Thanks, you can close this thread.
