I've tried following the instructions, I move the zip file into my lfs folder, but then when I right click, there is no "Extract to here" option, only "Extract all". This creates a folder, but doesn't seem to have installed the patch properly, as it does not say 0.5P2 at the bottom of the entry screen.

Can anyone help me please?

copy the files in the new folder to the root lfs directory? :s

If you are not sure about what you have extracted, create a new directory anywhere, extract the contents of the original zip to this new directory, copy the newly extracted contents of the new directory to your LFS directory overwriting the original files...

If you are a paranoid create a backup of your LFS system directory before overwriting the original files...

Ensure your LFS shortcut on your desktop is pointing towards the LFS.exe file that you have overwritten (incase you have multiple installations)
