Hi Zvika,

I recently upgraded to 2.1.2.5 and installed P4Merge, KDiff3, TortoiseMerge and Beyond Compare after upgrading. They all worked and SourceTree actually automatically found the source location.

I'm assuming you went into the Options screen from the Tools menu option to access the Diff tab to select the external diff tool from the drop-down for diff tool and merge tool?

Yes i did but it doesn't work image.png

I have the really same problem here.. Tried winmerge, kdiff3, diffmerge and no luck.

I tried to configure .gitconfig file without success. The message pops then disappear but nothing happens.

Does this work for anyone?

@TC I literally JUST got it working, the solution for me was to update the Embedded Git (2.14.1 at time of writing) and then external merge works for me. I don't believe this is automatically updated when you update sourcetree.

Note that external DIFF suddenly started working for me for no apparent reason a few weeks ago, maybe an update fixed it. So because diff was working but not merge, I took a look with Process Monitor to see if there was an obvious difference, but SourceTree just shells out to git.exe to actually launch the diff/merge tool, which pointed strongly to the embedded git or configuration as the problem.
