>From the Git Bash command line, I enter $ git difftool and type ?y? when the file I want to difference appears. Git correctly calls the external diff tool (LVCompare.exe), but the path for the remote file Git passes to that tool is malformed (e.g., C:\/Users/Paul/AppData/Local/Temp/QCpqLa_calcLoadCellExcitation.vi). Obviously the \/ (backslash forwardslash) combination is incorrect. For the record, I have successfully made calls to LVCompare.exe manually from a Windows command prompt directly (without Git). The relevant portion of the .gitconfig file is: [diff] tool = "LVCompare" [difftool "LVCompare"] cmd = 'C:/Program Files (x86)/National Instruments/Shared/LabVIEW Compare/LVCompare.exe' \"$LOCAL\" \"$REMOTE\" For the record, the operating system is Windows 8.1.
