Limits” button is not grayed out:
Console Root/Component Services/Computers -
right click on “My Computer” and select Properties. Go to COM Security,
Launch and Activation Permissions. (Since the “Edit Limits” button was
grayed out, no changes were made here)

Security Settings/Local Policies/Security Options: DCOM: Machine Launch Restrictions in Security Descriptor Definition Language
(SDDL) syntax
3.)Double click (or right click, properties), Edit Security, Add “Everyone” &
