Hi, this side Zoey, I am working as QuickBooks Technician for 5 years. I have years of experience dealing with QuickBooks Issues. Sometimes when you select the QuickBooks Desktop icon multiple times it shows “quickbooks won't open ” error. At that time, allow QuickBooks enough time to load before you continue. Still, you face won’t open or any kind of QB issue, So you can easily connect with me. I am 24/7 available for your technical Assistance.
