Clarification of the steps from via Support Beyond Compare to use Beyond Compare 3 or 2 from Visual Studio and with Team Foundation System.

First run this little batch file to show you the exact location of BComp.exe:

[sourececode language='text']
@echo off
call :show “%ProgramFiles%\Beyond Compare 3\BComp.exe”
call :show “%ProgramFiles(x86)%\Beyond Compare 3\BComp.exe”
call :show “%ProgramFiles%\Beyond Compare 2\BComp.exe”
call :show “%ProgramFiles(x86)%\Beyond Compare 2\BComp.exe”
goto :eof
:show
if not exist %1 goto :eof
echo Beyond Compare is here:
echo %~1
[/sourececode]

(I know that this will not find a Portable Beyond Compare installation).

Note that BComp.exe (for GUI use) and BComp.com (for console use) are bootstrappers for BCompare.exe. Both will wait when ran from a GUI or console for the comparison to finish. Starting BCompare.exe will not wait. See BComp.exe vs BComp.com – Scooter Forums for more information on this.

Everywhere you see path to BComp.exe below, enter the path that the above batch file tells you.

The first two pictures on the right show common steps for all three integrations. The images below are the specific ones for each integration. You can click on each image to view a larger version.

The steps work with the full version of Visual Studio and the Team Explorer edition of Visual Studio.
