System Writer is missing

Hi,

In one of the Server 2008 SP2 system writer is missing. I have below troubleshoots but still issue is there.

1) Restarted the "Cryptographic services"

2) Registered the DLL files

3) Rebooted the server.

4) Applied access to the files in %windir%\winsxs\filemaps\

Can anyone suggest what needs to checked to fix the issue.

Thanks in advance.
