Ok for some reason the read-only attribute is set on these files.
I am having to go to each subsequent one that the updater points out it can't access.
Couldn't you just have implemented something in the updater that force-deletes these files? I am running it with administrator privileges...
This really is a shoddy application of an updater.
Renamed MBII folder as suggested - same result, this time with a different file:
"Access to the path 'C:\Program Files (x86)\LucasArts\Star Wars Jedi Knight Jedi Academy\GameData\mbii.x86.exe' is denied.
Thanks
