Hey there, DoreenT.
QuickBooks Premier - Accountant Edition 2012 is a discontinued and no longer supported version of QuickBooks. Registering it online is currently unavailable. Intuit discontinues live support and access to add-on business services of older desktop versions of QuickBooks to focus on supporting more current versions.
You might want to consider upgrading your QuickBooks Desktop so you can continue and back to running your normal business processing.
However, if you want to keep your QuickBooks version, I'd suggest getting in touch with our Support Team to help you install and re-register the program using a validation code. Unlike in this public forum, they have the tools required to get the correct authentication code.
I'll be sharing with you this article: System requirements for QuickBooks 2020 and Enterprise Solutions 20.0. It contains information about the operating system, hardware, software, and other requirements to run QuickBooks Desktop.
Please know that you can always get back into this post if you have more questions. I'll keep an eye on your response. Have a good one.
