Problem launching DiffMerge using "git mergetool"

[bibroy]

When on windows, I am launching command "git mergetool", in order to resolve merge conflict, I am getting error as per attached screenshot - please help!

Note: when I do "git merge" (not using DiffMerge) - things appear normal!

Following is my .gitconfig file:
[user]
name = Bibhash Roy
email = bibhash@whitepeaksoft.com

[core]
editor = 'c:/program files/sublime text 3/subl.exe' -w
autocrlf = false
[diff]
tool = diffmerge
[difftool "diffmerge"]
cmd = F:/Bibhash/Programs/DiffMerge_4_2_0_697_stable_x64/sgdm.exe \"$LOCAL\" \"$REMOTE\"
[merge]
tool = diffmerge
[mergetool "diffmerge"]
trustExitCode = true
cmd = F:/Bibhash/Programs/DiffMerge_4_2_0_697_stable_x64/sgdm.exe /merge /result=\"$MERGED\" \"$LOCAL\" \"$BASE\" \"$REMOTE\"
[difftool]
prompt = false

I reinstalled diffmerge using msi installer (earlier used the zipped version) - the problem remains same.

Sorry I don't have a response yet. I'm getting a test setup to try this as well. I'm not sure why Git is passing the path as .\filename.

It took a while to figure this one out.

In your .git config, in the line that configures the merge tool, change /merge and /result to -merge and -result. Don't change anything about the lines relating to the diff tool, just merge.
