How about changing the code to something like:

var AcrobatInfo = (function() {
   var isInstalled = false,
       vern = null;
		
   function findPlugin(nme) {
     var p;
     for (key in navigator.plugins) {
       p = navigator.plugins[key];
       if (p.name == nme) return p;
     }
     return null;
   }

   (function() {
     var plugin;
		
     if (typeof window.ActiveXObject != "undefined") {
       // AcroPDF.PDF is used by version 7 and later
       // PDF.PdfCtrl is used by version 6 and earlier
       try {
         plugin = new ActiveXObject("AcroPDF.PDF");
         isInstalled = true;
       } catch(e) {}
       try {
         plugin = new ActiveXObject("PDF.PdfCtrl");
         isInstalled = true;
       } catch(e) {}
			
       if (plugin) {
         vern = plugin.GetVersions().split(',')[0].split('=')[1];
       }
     } else {
       plugin = findPlugin('Adobe Acrobat')
               || findPlugin('Chrome PDF Viewer')
               || findPlugin('WebKit built-in PDF');
			
       if (plugin) isInstalled = true;
       if (plugin && plugin.version) vern = plugin.version;
     }
       plugin = null;
     })();
	
     return {
       installed: isInstalled,
       version: vern
     };
})();


Usage

var a = "Acrobat is "
         + (AcrobatInfo.installed?"":"not")
         + " installed. "
         + AcrobatInfo.version;

One shortcoming is that while FF will return the full version string (eg 
10.1.7.27) IE 9 only returns part of the version string (eg 10.1.)
