And peterf1999, how calls (trigger to) the file AC2_arc.exe to run through setup ?

This simple inno setup's code does it (vcredist_x86.exe):

const
Subkey='Software\Ubisoft\Assassin'#39's Creed II';

function InitializeSetup(): Boolean;

var
ResultCode: integer; InL,InS: string;

begin
    // install Visual c++ Runtime Libraries (vcredist_x86_Install.exe)
    Exec (ExpandConstant('{src}\vcredist_x86_Install.exe'),'/Q', '', SW_SHOW,
    ewWaitUntilTerminated, ResultCode);
    // retrieve game's installation path from registry
    RegQueryStringValue(HKEY_LOCAL_MACHINE, Subkey,
      'InstallDir', InL);
    // remove trailing backslash from game's installation path
    InL:=RemoveBackslash(InL);
    // retrieve & set source drive letter
    InS:=ExpandConstant('{src}');
    SetLength(InS,2);
    // and finally extract AC2_arc contents to install location
    Exec (InS+'\AC2_arc.exe', '-x -d'+'"'+InL+'"'+' -y -s2', '', SW_SHOW,
      ewWaitUntilTerminated, ResultCode);
    // exit
    Result:=False
end;

(...) R6Vegas_Game.exe Executables R6Vegas_Launcher.exe (...)

Maybe the layout from Rainbow Six Vegas?
Thank you!

Yep, but its only an unlocked version of layout.bin that allows the repacking
