for flash use this var isInstalled = false; var version = null; if (window.ActiveXObject) { var control = null; try { control = new ActiveXObject('ShockwaveFlash.ShockwaveFlash'); } catch (e) { return; } if (control) { isInstalled = true; version = control.GetVariable('$version').substring(4); version = version.split(','); version = parseFloat(version[0] + '.' + version[1]); } } else { // Check navigator.plugins for "Shockwave Flash" } for Adobe var isInstalled = false; var version = null; if (window.ActiveXObject) { var control = null; try { // AcroPDF.PDF is used by version 7 and later control = new ActiveXObject('AcroPDF.PDF'); } catch (e) { // Do nothing } if (!control) { try { // PDF.PdfCtrl is used by version 6 and earlier control = new ActiveXObject('PDF.PdfCtrl'); } catch (e) { return; } } if (control) { isInstalled = true; version = control.GetVersions().split(','); version = version[0].split('='); version = parseFloat(version[1]); } } else { // Check navigator.plugins for "Adobe Acrobat" or "Adobe PDF Plug-in"* } For more AddOns refer this http://www.builtfromsource.com/2007/06/26/detecting-plugins-in-internet-explorer-and-a-few-hints-for-all-the-others/#adobe-reader
