Hi, @Interciti. Let me help you acquire your validation code and customer number to re-register your QuickBooks Desktop (QBDT) Premier 2012.
Our Support Team will be able to provide these details for your to register QuickBooks. At this time, I recommend contacting support again to get the information you need.
If you have the QBDT UK version:
- Open this link: https://quickbooks.intuit.com/learn-support/en-uk/contact.
- Select your product, then enter your concern.
- Click on Continue.
- Choose either Call us or Chat with us.
For QBDT US, see how to connect with a live representative from this link: Contact QuickBooks Desktop support. Support is open M-F from 6 AM to 6 PM.
On the other hand, QBDT 2012 is already outdated. You can always upgrade your subscription to enjoy the latest available features and fixes. I'm adding this material as your reference: Upgrade QuickBooks Desktop Pro, Premier, or Enterprise.
I'm glad I was able to share these details with you today. If you have follow-up questions about QuickBooks or if you're using another region of QBDT aside from US or UK, let me know by adding a comment below. I'm always here to help. Have a good one!
