External Diff SemanticMergeTool not working....

Question

I am currently reviewing SourceTree + SemanticMerge for our Enterprise development team (30+ developers), but when I invoke the External diff, it returns an error dialog box with the following message:

Item has already been added. Key in dictionary: 'home' key being added: 'HOME'

I am able to run the SemanticMerge as a standalone tool successfully.

Spec: Window 10, SourceTree 2.6.1, SemanticMerge 2.0.127, Git 2.18.0

here is my .gitconfig

[user]
name = Stephen Kong
email = zollen.kong@gmail.com
[core]
autocrlf = true
[difftool "sourcetree"]
cmd = 'C:/Users/zollen/AppData/Local/semanticmerge/semanticmergetool.exe' -s $LOCAL -d $REMOTE
prompt = false
[mergetool "sourcetree"]
cmd = 'C:/Users/zollen/AppData/Local/semanticmerge/semanticmergetool.exe' -s $REMOTE -d $LOCAL -b $BASE -r $MERGED
trustExitCode = true
prompt = false
keepBackup = false

You mean you are able to invoke Semantic Merge from SourceTree???

I am able to reproduce this issue with window 7 and window 10.

Let me see if I could reproduce the issue from my office.

Where is the error dialog box coming from? Is Semantic Merge the one giving it? Can you post a screenshot? I'm unable to reproduce the issue on my machine on both the enterprise and non-enterprise versions 😕

[difftool "sourcetree"]    
    cmd = 'C:/Users/zollen/AppData/Local/semanticmerge/semanticmergetool.exe' -s \"$LOCAL\" -d \"$REMOTE\"

OR

[difftool "sourcetree"]    
    cmd = 'C:/Users/zollen/AppData/Local/semanticmerge/semanticmergetool.exe' -s $LOCAL -d $REMOTE

Both scenarios do not work..
