This problem can be fixed through the following steps:

1. Find the application name

As you can notice there are two ID numbers in the error message: the CLSID and the APPID.
Take the APPID and search for the matching registry key under HKLM:\SOFTWARE\Classes\appid.

Get-ItemProperty 'HKLM:\SOFTWARE\Classes\appid\{9CA88EE3-ACB7-47C8-AFC4-AB702511C276}'

You will notice the application name.

3. Go to DCOM Config and in the menu select View by Details.
4. Find your application and notice the Application ID on the right which is the same than in the event message.
5. Right-click the application and select Properties
6. Select the Security tab. Note: If the buttons appear as grayed out, this means you didn’t set correctly the permissions on your account and you must go back to the former subtitle of this post.

     (S-1-5-18))
   • the type of missing permissions (in my example above: Local Activation)
8. Set permissions accordingly.
   In my example I would have following permissions to set:
