Hi Mark, Could you please send us the VisualSVN Server logs? VisualSVN Server writes log to the Windows Event Log. You could find VisualSVN Server logs in the Application category in the Event Viewer.
Please also try to use full path to svn.exe in hook script, i.e. hook script should be something like this: "%VISUALSVN_SERVER%\bin\svn.exe" -- Regards, Olga Dolidze VisualSVN Support
