Hello Monks, I am facing problem when trying to update a MS project task name cell color. here is my code.

Win32::OLE->FreeUnusedLibraries ();
Win32::OLE->Initialize(Win32::OLE::COINIT_MULTITHREADED);
my $app;
my $project;
eval{
    $app = Win32::OLE->new('MSProject.Application') or print "Couldn't
+ open project '$MSPfilename'\n";
    $app->{'DisplayAlerts'} = 0; 
    $app->{'Visible'}       = 0;
    $app->{'AskToUpdateLinks'} = 0;
    $app->OptionsGeneral(0,0,0);    
    $app->FileOpen($MSPfilename);
};

if ($@)
{
    my $msg = "A problem was encountered when accessing thefile '$MSPf
+ilename'\n" . Win32::OLE->LastError()."\n";
    print "$msg\n";
}
$project = $app->{Projects}->Item(1);

if($app)
{
    if (($project) && $project->Tasks)
    {
        my $count = $project->Tasks->Count();
        for my $indx (1..$project->Tasks->Count())
        {
            my $Task = $project->Tasks($indx);
            $Task->{Cell}->{Name}->{CellColor} = 1;
        }
    }#End of if appTasks loop.
    $project->Save();
}#End of if app loop.
$app->Quit();
