Nitro Unable to Validate Serial Number

[Maggie McNinch]

Hello,

I am trying to upgrade old Nitro Pro 9 Licenses but the system says: We were unable to validate your serial number. Please ensure you entered it correctly. If you believe you are eligible for an upgrade, please leave a post on our Community Forum and update us with your issue.

Please help!

Hello @ABC1234,

Thank you for reaching out to us through our Community Forums!

Since I am unable to pull-up your Nitro Pro 9, could you please provide its serial number?

Thank you very much in advance and I am looking forward to hearing back from you.

Hi. I purchased V13, installed it in my new Windows 10. But Nitro website would not recognize my key as valid one. So I cannot activate it.

Thanks for your help.

Hello @Joel D.,

Thank you for reaching out to us through our Community Forums!

Kindly note that our Activation Portal as of the moment can only accept serial numbers with format 23460x-xxxxxx-xxxxxx where 'x' are random numbers.

With the release of Nitro Pro 13, it is now using a different format (5049xxxxxxxxxxxxxx) and will soon be integrated into the same portal in the next coming months. As much as we would like to provide an ETA, it is not yet available.

If you would like to activate your program, kindly install it first on your machine using these direct installers:

x32 http://install.nitropdf.com/professional_1391155/en/retail/nitro_pro13_ba_x86.msi 
x64 http://install.nitropdf.com/professional_1391155/en/retail/nitro_pro13_ba_x64.msi

If you are not sure which to pick, this will help:  https://kb.gonitro.com/knowledgebase#/search/64/000003790

After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activate by entering your serial number

Thank you for choosing Nitro and I hope this helps!

Morning AllainU.

Thank you for replying to my request.

My Key does start with 504955XXXXXX.

I did what you suggested, unfortunately, I got the same result. It is saying that "Nitro Pro encountered an issue during activation".

What would you suggest to do now?

Thanks again.

Hi AllainU.

Thanks for your help, this is getting frustrating.

I cut and pace the screen shots as you asked. 

I got the same error message.

It says "There is an issue with the activation certificate" 

I could not attach the cut and insert doc.
