While installing Sitecore 9.1 XP0 using SIM (Sitecore Instance Manager), I have stumbled across the Sitecore.Marketing.Automation Service Failed to Start. After digging into event viewer, I came across below error

Faulting application name: maengine.exe, version: 3.0.0.0, time stamp: 0xc338dcf1 Faulting module name: KERNELBASE.dll, version: 10.0.19041.1466, time stamp: 0xe01c7650 Exception code: 0xe0434352 Fault offset: 0x0000000000034f69 Faulting process id: 0x2b5c Faulting application start time: 0x01d80c7cbbb87b1b Faulting application path: C:inetpubwwwrootsc-appsc-appXConnect.localApp_DatajobscontinuousAutomationEnginemaengine.exe Faulting module path: C:WindowsSystem32KERNELBASE.dll Report Id: 9676bc80-5063-40b9-92c0-bb71ad7785e0 Faulting package full name: Faulting package-relative application ID

This error can be resolved by providing “full control” rights to “Local Service” account to C:\inetpub\wwwroot\sc-app folder (parent folder of sc-app.local, sc-appxconnect.local). Sitecore Marketing Automation Service is running under “Local Service” account and requires access to this folder.

Also, please check if there are any unsigned certificates in the Trusted Root and move them into intermediate certificate store by running below commands in powershell.
