Cannot edit DCOM Config properties

I get an error from my event handler which suggests me to modify  the {000C101C-0000-0000-C000-000000000046} using the Component Services administrative Tool.

1. Administrative Tools ->  Component Services -> {000C101C-0000-0000-C000-000000000046}
2. Right click the {000C101C-0000-0000-C000-000000000046} and then select properties
3. Go to security tab and I cannot edit the "Launch and Activation Permission" and "Access Permissions" ad the choices are grayed out

After another searching, I know that I need to do something in Register Editor

1.  In cmd, type "regedit"
2. Go to HK_LOCAL_MACHINE\SOFTWARE\Classes\AppID\{000C101C-0000-0000-C000-000000000046}
3. Right click it and select permission and then click Adanced
4. Go to Owner tab and update Administrators ad the current Owner

5. Grant the administrators "Full Control"

6. Restart the Component Services

7. You can modify the Permissions now
