Hello, everyone. I'm Jessie, and I work in customer service. What are the methods to fix 'QuickBooks error 15241'? This is a question that many QuickBooks users ask me. Start by shutting off QuickBooks Desktop. Right-click on the Computer icon, then select Manage after tapping on the Windows Start button and then Services and Applications. Intuit QuickBooks FCS should be double-clicked. Tap Manual from the Startup type drop-down arrow on the General tab. Apply should be selected. Select Start and then OK. QuickBooks Desktop should now be open. Updates for QuickBooks Desktop are available for download.
