I am currently running Windows 10 Pro 1803 64-bit with QuickBook Pro 2017 Contractor edition. This is the desktop that is hosting a company file for 2 other networked computers. I am unable to start the QuickBooksDB27 service manually or automatically. If I try, it gives the Error 193: 0xc1, Unable to start the service error. I have tried giving the created QB local user admin privileges, changing the service to start as local service under admin account, and a complete clean install of QB Pro 2017. I have also tried file doctor with different company files and company file backups.
When I click on Host Multi-User Access, QB goes to a blank box like nothing is open, and after 15 seconds, the application crashes to desktop. Next time I open QB, it goes back into single-user mode just like I never clicked Host Multi-User Access. I can not switch to Multi-User mode.
Is there a fix for this? I have tried reinstalling QB 4 times with no success. I was only able to open the company file once I switched to single user mode and stopped hosting multi-user access. Now, I cannot enable it due to the seemingly corrupted service.
