I have tried to open my QuickBooks Pro Desktop 2017 and it just will not. It will bring up the round circle with the green dots then that goes away and nothing else happens. Once it gave me the message that QuickBooks was already running. I have checked the task manager and it does not show QuickBooks running. So what do I do? I am using Windows 10. Does this have something to do with the new update and not supporting the 2017 version now? Thank you for your help.
