You might want to try this: <script> var p; try { p = new ActiveXObject('AcroExch.Document'); } catch (e) { // active x object could not be created document.write('doesnt look like the PDF plugin is installed...'); } if (p) document.write('does look like the pdf plugin is installed!'); endif; </script> Tien Vo NEC Australia

  Try this
  /This script detects the following:
  //Flash
  //Windows Media Player
  //Java
  //Shockwave
  //RealPlayer
  //QuickTime
  //Acrobat Reader
  //SVG Viewer
  
  
  var agt=navigator.userAgent.toLowerCase();
  var ie = (agt.indexOf("msie") != -1);
  var ns = (navigator.appName.indexOf("Netscape") != -1);
  var win = ((agt.indexOf("win")!=-1) || (agt.indexOf("32bit")!=-1));
  var mac = (agt.indexOf("mac")!=-1);
  
  if (ie && win) { pluginlist = detectIE("Adobe.SVGCtl","SVG Viewer") + detectIE("SWCtl.SWCtl.1","Shockwave Director") + detectIE("ShockwaveFlash.ShockwaveFlash.1","Shockwave Flash") + detectIE("rmocx.RealPlayer G2 Control.1","RealPlayer") + detectIE("QuickTimeCheckObject.QuickTimeCheck.1","QuickTime") + detectIE("MediaPlayer.MediaPlayer.1","Windows Media Player") + detectIE("PDF.PdfCtrl.5","Acrobat Reader"); }
  if (ns || !win) {
  nse = ""; for (var i=0;i<navigator.mimeTypes.length;i++) nse += navigator.mimeTypes.type.toLowerCase();
  pluginlist = detectNS("image/svg-xml","SVG Viewer") + detectNS("application/x-director","Shockwave Director") + detectNS("application/x-shockwave-flash","Shockwave Flash") + detectNS("audio/x-pn-realaudio-plugin","RealPlayer") + detectNS("video/quicktime","QuickTime") + detectNS("application/x-mplayer2","Windows Media Player") + detectNS("application/pdf","Acrobat Reader");
  }
  
  function detectIE(ClassID,name) { result = false; document.write('<SCRIPT LANGUAGE=VBScript>\n on error resume next \n result = IsObject(CreateObject("' + ClassID + '"))</SCRIPT>\n'); if (result) return name+','; else return ''; }
  function detectNS(ClassID,name) { n = ""; if (nse.indexOf(ClassID) != -1) if (navigator.mimeTypes[ClassID].enabledPlugin != null) n = name+","; return n; }
  
  pluginlist += navigator.javaEnabled() ? "Java," : "";
  if (pluginlist.length > 0) pluginlist = pluginlist.substring(0,pluginlist.length-1);
  
  //SAMPLE USAGE- detect "Flash"
  //if (pluginlist.indexOf("Flash")!=-1)
  //document.write("You have flash installed")

  Here's the full javascript code to detect any version of Acrobat:
  
  This works both for IE and NS and any version of Acrobat :)
  Hope it helps someone!
  
  the problem with the other scripts is that it doesn't work for Acrobat 7.0 as the type changed from PDF.PdfCtrl.version to AcroPDF.PDF.1
  
  this code corrects that problem!
  
  feedback appreciated!
  
  
  
  
  var acrobat=new Object();
  
  acrobat.installed=false;
  acrobat.version='0.0';
  
  if (navigator.plugins && navigator.plugins.length)
  {
  for (x=0; x {
  if (navigator.plugins[x].description.indexOf('Adobe Acrobat') != -1)
  {
  acrobat.version=parseFloat(navigator.plugins[x].description.split('Version ')[1]);
  
  if (acrobat.version.toString().length == 1) acrobat.version+='.0';
  
  acrobat.installed=true;
  break;
  }
  }
  }
  else if (window.ActiveXObject)
  {
  for (x=2; x<10; x++)
  {
  try
  {
  oAcro=eval("new ActiveXObject('PDF.PdfCtrl."+x+"');");
  if (oAcro)
  {
  acrobat.installed=true;
  acrobat.version=x+'.0';
  }
  }
  catch(e) {}
  }
  
  try
  {
  oAcro4=new ActiveXObject('PDF.PdfCtrl.1');
  if (oAcro4)
  {
  acrobat.installed=true;
  acrobat.version='4.0';
  }
  }
  catch(e) {}
  
  try
  {
  oAcro7=new ActiveXObject('AcroPDF.PDF.1');
  if (oAcro7)
  {
  acrobat.installed=true;
  acrobat.version='7.0';
  }
  }
  catch(e) {}
  
  }

  It iterates through an array of plugins. Missing piece of code can looks like:
  
  for ( var x = 0, l = navigator.plugins.length; x < l; ++x )
  {
  ...
  }

  I've used the following objects:
  
  Scripting.FileSystemObject
  Outlook.Application
  Word.Application
  Excel.Application
  
  Remember that Javascript now has try...catch() syntax which I've successfully used to degrade gracefully if creating one of these objects fails (because it isn't installed/isn't working properly etc).
  
  Also remember to quit word [objWord.Quit()] on the onUnload event of the page, otherwise you'll build up quite a little collection of WINWOD.EXE processes... these WILL eventually crash your computer ;-)
  
  Good luck.

  Why is navigator.plugins still empty in IE 6.0?
  var objWord = new ActiveXObject("Word.Application"); always give the message
  "An ActiveX control on this page might be unsafe to interact with other parts of the page. Do you want to allow this interaction?"
  
  which is really a irritating to a user...it would be nice to have some other workaround...
