Ran install.ps1 same issue as post 198(I've pasted the MDE log below). I think that's the last piece to the puzzle, once we can get the sense service to start I should work

0x51B means an owner issue, so please try to import the Sense Service key again using FRST and PSExec, maybe it will show another error if it fails.

Please follow these instructions to run the
577bf0efb8088-FRST.png
Farbar Recovery Scan Tool with system privileges.

Download the 64 bit version: - Farbar Recovery Scan Tool Link

Warning: This script was written specifically for this system. Do not run this script on another system.
  • Download PsExec from Microsoft Sysinternals to your desktop.
  • Unzip PsTools.zip to its own directory on the system drive, for example: C:\Tools\PsTools
  • Navigate in an elevated command prompt to the PsTools directory: cd C:\Tools\PsTools.
  • Now copy and paste the following command into the command prompt and press enter. Click on the Agree button when the licence agreement of PsExec appears.
  • Note: Ensure that both FRST64.exe and the Fixlist.txt file are on your desktop! Otherwise you'll need to ammend the command to the right location.
    Code: 
    psexec -i -d -s "%userprofile%\desktop\FRST64.exe"
  • FRST will make a new backup of the registry first, please wait until this process is completed.
  • Ensure the provided Fixlist.txt is in the same location as FRST64.exe and then press the Fix button.
  • If for some reason the tool needs a restart, please make sure you let the system restart normally.
  • When finished, a log called Fixlog.txt will appear in the same directory the tool is run from.
  • Post the logfile Fixlog.txt as attachment in your next reply.

Ran the above, log attached. Unable to start either service sense or WinDefend. I was actually thinking it could be permissions as when I try to change Windefend from manual to auto start I see the below.

also rebooted and tried to start sense and windefend (no joy)
