How do i fix QuickBooks Error 6000 77?

Hi there, @MarthaCPA.

Thanks for sharing the troubleshooting steps you've made to resolve the Error -6000, -77.

If you've already performed all of the listed fixes, I'd recommend doing a clean install. These steps will help us refresh the product and fix the error.

Let's start by uninstalling QuickBooks Desktop. Here's how:

1. Open the Windows Start menu. Search for “Control Panel” and open Control Panel.
2. Click Programs and Features or Uninstall a Program.
3. From the list of programs, select the version of QuickBooks Desktop you want to uninstall.
4. Click Uninstall/Change and then Remove.  Select Next.  If you don’t see this option, sign out and sign back in to Windows as an admin (or a user with admin rights).

When you're done, reinstall QuickBooks Desktop.

If you're still getting the same result, move to solution 2 in this article: Uninstall QuickBooks and manually rename the installation folders.

Please keep me posted on how it goes. Let me know in the comments if you have other QuickBooks error code concerns and questions on how to fix them. I'm always around to help. Take care, and I wish you continued success, @MarthaCPA.
