Microsoft last night released KB4338548 (OS Build 17134.83) for Windows 10 April 2018 Update PCs. This update fixes an issue where the 2017 and 2018 versions of Intuit QuickBooks Desktop can’t run in multi-user mode.
The QuickBooks multi-user mode service fails to start with error “Windows could not start the QuickBooksDBXX service on Local Computer.” and “Error 193: 0xc1”.
Microsoft noted that there is no known issue in this build. You can download this update through Windows Update on your PC.
