How to configure kDiff3 as merge tool for Android Studio

I have been loosing code due to poor merging built in to Android Studio (using SVN for source control) how can I configure kDiff3 as the merge tool which Android Studio will use for diff and merge.

File > Settings... > Tools > Diff > External Diff Tools

Tick the check box "User external diff tool"
Path to executable: {Program Files}\KDiff3\Kdiff3.exe
