I have taken the DB offline and back online with some success in this situation, just a thought.

You just need two top level folders, one for each instance:

<?xml version="1.0" encoding="utf-8"?>

<DtsServiceConfiguration xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

<StopExecutingPackagesOnShutdown>true</StopExecutingPackagesOnShutdown>

<TopLevelFolders>

<Folder xsi:type="SqlServerFolder">

<Name>MSDB</Name>

...

Thank you much, looks good.

For example, if your instance name is MSData:

<TopLevelFolders>

<Folder xsi:type="SqlServerFolder">

<Name>MSDB</Name>

<ServerName>\MsData</ServerName>

...

No problem, just meant that if you are doing named instances, have to add them in the xml file.

This process worked for me:

Verify account is member of Distributed COM Users

@ Component services, My Computer, DCOM Config, Microsoft SQL Server Integration services 11.0, Properties, Security, add account

OK

Edit <Install...

I found this link helpful for that same scenario, the permission changes you need are defined in the section Eliminating the "Access is Denied" Error:
