function InitializeSetup(): Boolean;
var
  ResultCode: Integer;
begin
  if not FontExists('My Font') then
  begin
    ExtractTemporaryFile('MyFont.ttf');
    ExtractTemporaryFile('FontReg.exe');
    Exec(ExpandConstant('{tmp}\FontReg.exe'), '/copy', '', SW_HIDE, ewWaitUntilTerminated, ResultCode);
  end;


  Result:= True;
end;

could you test this?

function InitializeSetup(): Boolean;
begin
{ Font }
  ExtractTemporaryFile('{#MyFont1}');
  ExtractTemporaryFile('{#MyFont2}');

  InstallFMXFont(ExpandConstant('{tmp}\{#MyFont1}'));
  InstallFMXFont(ExpandConstant('{tmp}\{#MyFont2}'));
{ Font }

  FMXInnoInit;

  Result := True;
end;

procedure DeinitializeSetup();
begin
{ Font }
  DeleteFMXFont(ExpandConstant('{tmp}\{#MyFont1}'));
  DeleteFMXFont(ExpandConstant('{tmp}\{#MyFont2}'));
{ Font }

  FMXInnoShutDown;
end;


procedure FMXDesigning;
begin
  { FMX Blank Form }
  FMXForm.FCreateBlankForm(WizardForm.Handle, ALCrimson, '');
  FMXForm.SetCursor(ExtractAndLoad('Dark2.ani'));
    // Font
  InvalidateFMXFont;

  ....

end;
