I'm here to help you get past the error so you can update your QuickBooks Desktop.
The error 12007 is caused by QuickBooks Desktop not being able to utilize the internet connection on your computer. These errors can also be caused by general internet connection failures.
Let's perform a couple of troubleshooting steps to resolve this error. First, we'll need to verify if you can access a secure website outside of QuickBooks Desktop, such as the sign-in page of your financial institution.
If you are unable to do so, I recommend consulting a computer or IT expert. Once done, please follow the steps provided in this article: Error 12XXX when getting updates.
