Using mmc command-line options, you can open a specific mmc console, open mmc in author mode, or specify that the 32-bit or 64-bit version of mmc is opened.

Syntax

mmc <path>\<filename>.msc [/a] [/64] [/32]

Parameters

Parameter Description
<path>\<filename>.msc starts mmc and opens a saved console. You need to specify the complete path and file name for the saved console file. If you do not specify a console file, mmc opens a new console.
/a Opens a saved console in author mode. Used to make changes to saved consoles.
/64 Opens the 64-bit version of mmc (mmc64). Use this option only if you are running a Microsoft 64-bit operating system and want to use a 64-bit snap-in.
/32 Opens the 32-bit version of mmc (mmc32). When running a Microsoft 64-bit operating system, you can run 32-bit snap-ins by opening mmc with this command-line option when you have 32-bit only snap-ins.

Remarks

  • You can use environment variables to create command lines or shortcuts that don't depend on the explicit location of console files. For instance, if the path to a console file is in the system folder (for example, mmc c:\winnt\system32\console_name.msc), you can use the expandable data string %systemroot% to specify the location (mmc%systemroot%\system32\console_name.msc). This may be useful if you're delegating tasks to people in your organization who are working on different computers.

  • When consoles are opened using the /a option, they're opened in author mode, regardless of their default mode. This doesn't permanently change the default mode setting for files; when you omit this option, mmc opens console files according to their default mode settings.

  • After you open mmc or a console file in author mode, you can open any existing console by clicking Open on the Console menu.

  • You can use the command line to create shortcuts for opening mmc and saved consoles. A command-line command works with the Run command on the Start menu, in any command-prompt window, in shortcuts, or in any batch file or program that calls the command.
