I downloaded version 3.1.2.0 to XP for testing and ran into the same problem.
Program would run but no files in the destination appeared.
The following resolved the problem for me:
The installation routine drops a copy of ROBOCOPY.EXE (The actual program
itself) into the 'C:\Documents and Settings\USERNAME\Application
Data\Robocopy GUI\Config folder.
The RobocopyGUI program cannot find it there, so it does not work.
The easiest fix is to drop a copy of Robocopy.exe in the c:\Windows
directory where it will be in the path. THEN the Robocopy GUI program will
work properly.

Post by Canes4LifeAnyone familiar with Robocopy GUI? I downloaded the tool and tried a
folder/file copy from one directory to another. Nothing happens and no
errors appear.
