He I am having real problems installing this version of SEP on a Windows XP SP3 machine

Have have already looked on the forums for this problem and tried the following

Running Cleanwipe

Removing the following Reg Key

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\PendingFileRenameOperations

The reg key was present and I removed it and then rebooted, checked that the key was not re-created, but still could not install SEP on the machine.

Below are some snippets from the SEP_INST.log any help would be really appreaciated.

I also ran the SEP Support Tool and this reported that there were no problems.
