New Computer now I can't use Nitro

[Sandra Ollier]

I purchased Nitro a while back and paid in full the "one time fee".  I just got a new computer this past week and now it won't let me download Nitro and it is saying, 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  whenever I enter my serial number.  I am frustrated because it appears I am going to have to repurchase nitro for another "one time fee"  and I just wont be able to do that.

Thank you,

Sandra

Hello @Sandra Ollier,

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

Please note that we no longer support Nitro Pro 12

We recommend upgrading to our latest version, Nitro PDF Pro 14, which comes with significant stability and security improvements, as well as many feature enhancements, in particular in conversion and OCR functions. To upgrade to Nitro PDF Pro 14 at a discounted rate, please visit our Upgrade page https://www.gonitro.com/pro/upgrade 

To know more about some enhancements and fixes with Nitro PDF Pro 14, please visit our Release Notes page https://www.gonitro.com/product-details/release-notes 

In addition to that and many other feature improvements, version 14 also contains some important security vulnerability fixes that you might want to consider when deciding whether to upgrade to it or not. You can find out more about these fixes here: https://www.gonitro.com/nps/security/updates 

Alternatively, you can upgrade to the latest build of Nitro Pro 12. Per our Sunset Policy, https://www.gonitro.com/nps/product-details/sunset-policy , we stopped making feature enhancements to version 12 once we released Nitro PDF Pro 13 (Q4 2019). 

You can find these Nitro Pro 12.16.9.574 installers and activate it with your current serial number 234600-uvwxyz-868893:

x32 http://install.nitropdf.com/professional_12169574/en/retail/nitro_pro12_ba_x86.msi
x64 http://install.nitropdf.com/professional_12169574/en/retail/nitro_pro12_ba_x64.msi 

To know if you have 32-bit or 64-bit, please refer to this article:

Important: If you are using Chrome or any of the Chromium-based browsers (e.g., Vivaldi, etc.) and you are unable to access the above installer links, you're more than likely experiencing the results of a new security feature that was silently pushed out to the browsers, which blocks .exe/.msi/etc downloads without any visible error or prompt on the browser's frontend user space. To bypass this, please try these steps:

a. Right-click the link you're trying to download, and select "Save link as..."
b. Choose your save location and select "Save"
c. On the bottom edge of your browser window, the Downloads bar should now appear and the file will show up with a red error icon, attempting to block the download. Press the caret button and select "Keep"

Thank you for choosing Nitro and I hope this helps.
