For a work around try doing this:
http://support.veritas.com/docs/276221
Otherwise you can try:
>Right-click the windowsupdate.log file, and then select Properties
>Click the Security tab
>Under Groups and User Names add System
>Click the System account, click Deny - Full Control to change all of the permissions to Deny, and then click OK
>Restart the computer
>Once logged on the computer, rename the windowsupdate.log file to windowsupdate.old
>Then start the IDR Preparation Wizard
>Reboot the server once the IDR wizard is completed. This will recreate a new windowsupdate.log file at startup.
