Hi Sean,
I have tried and Windows will not allow it as the file it replaces is used by another application.
I tried booting in safe mode with fences disabled in the startup and it still happens.
Would you have any suggestion?
Kind regards,
Roland
In Taskmanager\Startup, stop Fences from starting up 1st:

Reboot, replace, change them to 'Enabled' again, reboot.
