    <p>
        Modern Windows versions support multiple users accounts on a single computer, each
        with different privileges. For security reasons, the privileges of applications
        can also be limited. For an installer, the <i>execution level</i> and <i>installation
            mode</i> are important. The execution level determines the privileges of the
        installer application. For example, to install hardware drivers, administrator privileges
        are required. Applications can also be installed for a single user or for all users
        on a computer, which is determined by the installation mode. Installation for all
        users requires a higher execution level as compared with a single user setup. The
        MultiUser.nsh header files provides the features to automatically handle all these
        aspects related to user accounts and installer privileges.</p>
    <p>
        Note that all settings need to be set before including the MultiUser.nsh header
        file.</p>
    <h2>
        Initialization and <a name="executionlevel"></a>Execution Level&nbsp;</h2>
    <p>
        Before the MultiUser.nsh file is included, the MULTIUSER_EXECUTIONLEVEL define should
        be set to one of the following values depending on the execution level that is required:</p>

        Insert the MULTIUSER_INIT and MULTIUSER_UNINT macros in the .onInit and un.onInit
        function to verify these privileges. If no uninstaller is created in the script,
        set MULTIUSER_NOUNINSTALL.</p>
    <blockquote>
        <pre>!define MULTIUSER_EXECUTIONLEVEL Highest
;!define MULTIUSER_NOUNINSTALL ;Uncomment if no uninstaller is created
!include MultiUser.nsh

Function un.onInit
  !insertmacro MULTIUSER_UNINIT

    </blockquote>
    <p>
        Whether the required privileges can be obtained depends on the user that starts
        the installer:</p>
    <ul>
        <li>Windows NT 4/2000/XP/2003 give the installer the same privileges as the user itself.
            If the privileges of the user are not sufficient (e.g. Admin level is required is
            set but the user has no administrator rights), the macros will display an error
            message and quit the installer. If is however possible to manually run the installer
            with an administrator account.</li>
        <li>Windows Vista restricts the privileges of all applications by default. Depending
            on requested execution level, MultiUser.nsh will set the RequestExecutionLevel flag
            to request privileges. The user will be asked for confirmation and (if necessary)
            for an administrator password.</li>
        <li>Windows 95/98/98 do not set any restrictions on users or applications. Administrator
            rights are always available.</li>
    </ul>
    <p>
        It is recommended to insert these initialization macros before macros that require
        user intervention. For example, it does not make sense to ask a user for an installer
        language if the installer will quit afterwards because the user account does not
        have the required privileges. After the macros are inserted, the variable $MultiUser.Privileges
        will contain the current execution level (Admin, Power, User or Guest).</p>
    <p>
        The following additional settings are available to customize the initialization:</p>
    <table>

    <p>
        As mentioned before, applications can both be installed for a single users or for
        all users on a computer. Applications for all users are typically installed in the
        Program Files folder and appear in the Start Menu of every user. On the contrary,
        applications for a single user are usually installed in the local Application Data
        folder and only a appear in the Start Menu of the user who installed the application.</p>
    <p>
        By default, MultiUser.nsh will set the installation mode for a per-machine installation
        if Administrator or Power User rights are available (this is always the case if
        the execution level is set to Admin or Power, if Highest is set it depends on the
        user account). For the Standard execution level the installation will always be
        for a single user. On Windows 95/98/Me installation for a single user is not possible.</p>
    <p>
        The following settings are available to change the default installation mode:
        <table>
            <tr>
                <td>
                    <b>Setting</b>

                <td>
                    Set default to a per-user installation, even if the rights for a per-machine installation
                    are available.

            </tr>

                    Non-empty registry key that is created during the installation in either HKCU or
                    HKLM. The default installation mode will automatically be set to the previously
                    selected mode depending on the location of the key.
                </td>
            </tr>
        </table>
        <p>
            After initialization, the variable $MultiUser.InstallMode will contain the current
            installation mode (AllUsers or CurrentUser).
        </p>
        <h3>
            Mixed-Mode Installation</h3>
        <p>
            For the Admin and Power levels, both a per-machine as well as a per-user installation
            is possible. If the Highest level is set and the user is an Administrator or Power
            User, both options are also available.</p>
        <p>
            Usually it's a good thing to give the user to choice between these options. For
            users of the Modern UI version 2, a page is provided that asks the user for the
            installation mode. To use this page, define MULTIUSER_MUI before including User.nsh.
            Then, the MULTIUSER_PAGE_INSTALLMODE macro can be used just like a normal Modern
            UI page (this page will automatically be skipped when running Windows 95/98/Me):</p>
        <pre>!define MULTIUSER_EXECUTIONLEVEL Highest
<b>!define MULTIUSER_MUI</b>
!define MULTIUSER_INSTALLMODE_COMMANDLINE
!include MultiUser.nsh
!include MUI2.nsh

!insertmacro MUI_LANGUAGE English

...

Function .onInit
  !insertmacro MULTIUSER_INIT
FunctionEnd

Function un.onInit
  !insertmacro MULTIUSER_UNINIT
FunctionEnd
</pre>
        <p>
            The MULTIUSER_INSTALLMODE_COMMANDLINE setting that also appears in this example
            enables the installation mode to be set using the /AllUsers or /CurrentUser command
            line parameters. This is especially useful for silent setup.</p>
        <p>
            The following settings can be used to customize the texts on the page (in addition
            to the general Modern UI page settings):</p>
        <table>
