Hy! After install Winrar with unattended SFX I want to load my winrar settings using this command in SFX comment: setup=copy settings.reg "%appdata%\winrar\" /yof course settings.reg is in ProgramFiles\WinRar WinRAR SFX return : Windows cannot find 'copy' ... If I use Setup=use.batWhere use.bat file contain the same copy code (without setup= ) all work nice. SFX don't support copy command or syntax error ? thanks for help
