If set, the iMacros Browser will replay the macro in silent mode. The browser window will not be seen and no icon in the Windows System Tray will indicate that iMacros is running. The process can only seen in the Windows Task Manager. It can be used also with iMacros.Sidebar.exe. In this case, the iMacros sidebar is not seen, but IE is still visible.
No value required.
imacros.exe -macro test1 -silent
