optimization...

hi,
we have used xtreeme toolkit 12.0.1 in our application.
The size of exe was 6MB now its 12 MB...
we have used ribbonbars in following way

    CXTPCommandBars* pCommandBars = GetCommandBars();
    m_pTabGalleries = pRibbonBar->AddTab(ID_GALLERIES_TAB);

    //'/Group Gallaries for buttons and combo box....
    CXTPRibbonGroup* pGroupGallaries = m_pTabGalleries->AddGroup(ID_GALLERIES_GROUP_GALLARY);
    pGroupGallaries->SetCaption( g_Interface.GetFromStringTable(IDS_GALLARIES));
    pGroupGallaries->SetControlsGrouping();
    pGroupGallaries->AllowReduce(0);

    //'/Button 'ClipArts'.
    m_pClipArtsButton = (CXTPControlButton*)pGroupGallaries->Add(xtpControlButton, IDC_CLIPARTS);
    m_pClipArtsButton->SetStyle(xtpButtonIconAndCaptionBelow);
    UINT uiClipArts[] = {IDC_CLIPARTS};
    pCommandBars->GetImageManager()->SetIcons(IDR_PNG_CLIP_ART, uiClipArts, _countof(uiClipArts), CSize(27, 23));//CSize(32, 32));
    m_pClipArtsButton->SetTooltip(g_Interface.GetFromStringTable(IDS_BTMPARENT_BTN_CLIPART));
    m_pClipArtsButton->SetHeight(30);//(35)
    m_pClipArtsButton->SetWidth(40);


but we havent found any way to free the memory or to optimize the memory
what we can do to minimize the size and to optimize or to free the xtp controls?
