SFC Can't create CLSID on system keys

Hi,
I want to add a new key name and value in a registry key under hkcr
\clsid\{guid}\InProcServer32
with This is for Windows 7

( the key hkcr\CLSID\{EA502722-A23D-11D1-A7D3-0000F87571E3} existing
on the system. I want to add one sub key under this key)

I have added this key in component.

But I am not able to create the key.
The MSI log says.

SFC: The following entry was not added, because its key is protected
by Windows: Key: \Software\Classes\CLSID\{EA502722-A23D-11D1-
A7D3-0000F87571E3}\s
erver Name:

SFC: Cannot create the following key due to windows protection:
\Software\Classes\CLSID\{EA502722-A23D-11D1-A7D3-0000F87571E3}

I there a way or some attributes so that i create the keys here ?

Does LockPermissions table help here ?

Please let me know.
