The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID
{*CLSID*}
and APPID
{*APPID*}
to the user NT AUTHORITY\SYSTEM SID (S-1-5-18) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.
Open regedit
Go to HKEY_CLASSES_ROOT\CLSID\{*CLSID*}
Right-click and select Permissions…
Advanced
If Owner is TrustedInstaller, change it to Administrators
Grant Administrators Full Control
Write down the application under Default
OK…
Go to HKEY_CLASSES_ROOT\AppID\{*AppID*} and do the same
Win-X > Control Panel > Administrative Tools > Component Services
Component Services >
Computers > My Computer > DCOM Config
Locate the application (sometimes it is the default name under the {*CLSID*}
entry, sometimes just the {*AppID*})
Right-click, select Properties, go to Security tab
In Launch and Activation Permissions, select Customize and Edit
Grant Local Activation to SYSTEM (first adding it if necessary)
Close Component Services
If you had to change ownership for {*CLSID*} or {*APPID*}, revert to the original
Do the same for the Administrators rights
Close regedit and restart the system
