Install-SitecoreConfiguration : Failed to start service Sitecore Marketing Automation Engine

I do not know if you are so lucky as I am … but every time when I am trying to install a new version of vanilla Sitecore on my local instance I have got issues which did not appear for other developers.

This time during installation of Sitecore 9.1 which should take 10-15 minutes I noticed that XP0-SingleDeveloper.ps1 script starts and stops more or less in the middle of whole installation process with following error: 

[---------------------------------- XConnectXP0_StartServices [2] : ManageService --------------------------------------------------]

I spent few hours trying to fix that. Based on previous experiences with Sitecore 9 and issues which I had with certificates I checked if my xConnect is accessible from the browser – it wasn’t. So I knew why I saw that error. 

Usually, when I had an issue with certificates I had to just add those certificates to the trusted list with mmc tool (more details here) but not this time. 

I started to search for solution in the internet and found following articles: 


The third link has been mentioned in the second link as a solution. In my case, this didn’t help but suggested the solution.

Powershell scripts were moving certificates to Intermediate Certification Authorities category – in theory it should be enough … in my case didn’t change anything so I checked what I had in this directory. 

I found out that DO_NOT_TRUST_SitecoreRootCert was added there many times. That was signal to me that it seems to be an issue. I deleted all of them before I tried install Sitecore again. And it worked! 

Currently, after installation I have got just one SitecoreRootCert.
