How can my app use MY FONTS? not user's

Can someone please tell me the neatest way to make sure my app uses
fonts that I can provide, rather than the nearest font the user has
installed on their system?  I have tried copying a #.ttf file into the
users windows\system directory but the app still can't pick it up.

type
TForm1=class( TForm )
procedure FormCreate(Sender: TObject);
procedure FormDestroy(Sender: TObject);
...
private
{ Private declarations }
bLoadedFont: boolean;
public
{ Public declarations }
end;

procedure TForm1.FormCreate(Sender: TObject);

var
sAppDir: string;
sFontRes: string;

begin
sAppDir := Application.ExeName;
sAppDir := copy( sAppDir, 1, rpos( '\', sAppDir ) );

sFontRes := sAppDir + 'MYFONT.FOT';
if not FileExists( sFontRes ) then
begin
sFontRes := sFontRes + #0;
sFont := sAppDir + 'MYFONT.TTF' + #0;
CreateScalableFontResource( 0, @sFontRes[ 1 ], @sFont[ 1 ], nil );
end;

sFontRes := sAppDir + 'MYFONT.FOT';
if FileExists( sFontRes ) then
begin
sFontRes := sFontRes + #0;
if AddFontResource( @sFontRes[ 1 ] ) = 0 then
bLoadedFont := false
else
begin
bLoadedFont := true;
SendMessage( HWND_BROADCAST, WM_FONTCHANGE, 0, 0 );
end;
end;

...
end;

procedure TForm1.FormDestroy(Sender: TObject);

var
sFontRes: string;

begin
if bLoadedFont then
begin
sFontRes := sAppDir + 'MYFONT.FOT' + #0;
RemoveFontResource( @sFontRes[ 1 ] );
SendMessage( HWND_BROADCAST, WM_FONTCHANGE, 0, 0 );
end;
end;

var
sAppDir, sFontRes: string;
begin
{...other code...}
sAppDir := extractfilepath(Application.ExeName);

sFontRes := sAppDir + 'MYFONT.TTF';
if FileExists( sFontRes ) then
begin
sFontRes := sFontRes + #0;
if AddFontResource( @sFontRes[ 1 ] ) = 0 then
bLoadedFont := false
else
begin
bLoadedFont := true;
SendMessage( HWND_BROADCAST, WM_FONTCHANGE, 0, 0);
end;
end;
{...}
end; {FormCreate}

var
sFontRes, sAppDir: string;
begin
{...other code...}

if bLoadedFont then
begin
sAppDir := extractfilepath(Application.ExeName);
sFontRes := sAppDir + 'MYFONT.TTF' + #0;
RemoveFontResource( @sFontRes[ 1 ] );
SendMessage( HWND_BROADCAST, WM_FONTCHANGE, 0, 0 );
end;

{...other code...}
end; {FormDestroy}
