Unable to select Beyond Compare as "External Diff Tool" to make external diff work

[sunk818]

I use Beyond Compare 4 as my External Diff comparison tool.

I selected it from the Dropdown list, but it does not seem to work. Perhaps the dropdown is based on an older version?

I also couldn't use a Custom > Diff Command unless I used c:\progra~1 instead of c:\program files. I tried wrapping c:\program files in double quotes, but that didn't make a difference.

The program location is: C:\Program Files\Beyond Compare 4\BCompare.exe

I had to configure Custom as c:\progra~1\beyond~1\bcompare.exe to make the external diff to work.

Not intuitive.

I'm having problems also – Windows 7, SourceTree 1.8.2.3, Beyond Compare 4

I tried the suggestion above - using c:\progra~1\beyond~1\BCompare.exe, but that doesn't work for me. 

Why doesn't the standard "Beyond Compare" from the External diff tool pulldown just work? Why do we need to do the Custom setup at all?? 

Very frustrating.
