The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID
{E579AB5F-1CC4-44B4-BED9-DE0991FF0623}
and APPID
{56BE716B-2F76-4DFA-8702-67AE10044F0B}
to the user domain\user SID (S-1-5-21-*) 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.
These Errors occur when CrashPlan runs as the user and tries to backup open files with the Volume Shadow Copy Service (VSS).
To fix the issue, change the permission in the registry then set the permission in DCOM.
