Greetings, @DA01.
It's great to see a new face here in the Community. Allow me to share some details about this issue.
QuickBooks Enterprise is a version of desktop. When you uninstall it removes the program and then program files, but the company file isn't removed. The company file will be the same when you open it after reinstalling.
The best route for this situation would be to use the steps above that I listed to fix the problem.
If this doesn't help, you can reach back out to me and I'll do my very best to get this resolved for you as soon as possible. I'm only a post away if you need me. Take care!
