I've been looking for the silver bullet solution to using KDiff3 as my git mergetool on Windows (using Git GUI).  I've finally got a solution that works in every Windows environment I've tried:

1. Add the KDiff3 directory to your Windows System Path (e.g. C:\Program Files\KDiff3\)
2. Add kdiff3 as your Git mergetool (From Git Bash, run git config --global merge.tool kdiff3)
3. Add kdiff3 complete path to Git Config (From Git Bash, run git config --global meregtool.kdiff3.path "C:/Program Files/KDiff3/kdiff3.exe")
4. Go into Git GUI settings and set the mergetool to kdiff3 (if Git GUI doesn't pick up this setting from git config, which it should)

Regardless of what I tried and/or read online, setting all possible settings is the only way KDiff3 works every time I select "Run Merge Tool" from the Git GUI right-click menu when there is a merge conflict.
