I can't open Quickbooks Desktop Pro. Tool Hub has been stalled from over 2 hours

Let's get your QuickBooks working, Neil25.

There are different reasons why QuickBooks won't open. It could be there is a damaged QuickBooks or Windows component on the system, or etc.

The QuickBooks Tools Hub is one of the solutions that we suggest. However, we have additional solutions if that won't work. You can follow Solutions 2- 5 in this article for more details: QuickBooks Desktop doesn't start or won't open.

If it is necessary for you to fix the .NET framework manually, you can follow the detailed guide in this link: Manually fix Microsoft .NET Framework errors.

Let me know how this goes so we can further assist you in getting your QuickBooks to work.

Thanks James,  I finally closed the cmd.exe window after I tried again to open Quickbooks. Then I closed all the other open programs on my computer and rebooted the computer. Then opened the Tool Hub again and trying once more to find out if it finishes this time. Left it for over an hour and it is stuck on "Repairing .Net 4.6 (Please wait - Do Not Close)" again.  I tried looking the task manager for CPU, memory and Disk usage to see if something was still processing but I don't see much going on there.  If no change after a while I will close the cmd.exe window and try what you suggested. Your input and ideas are very much appreciated.
