PDFObject.js IE6報錯 automation 服務器不能創建對象

附件預覽之前一直採用將pdf文件轉成swf文件然後再用flash預覽，可是有些客戶端是禁止安裝flash，於是就採用PDFObject.js，在虛擬機中調試PDFObject.js，一直報錯：automation 服務器不能創建對象，調試了一會，查閱了下源碼，才意識到是虛擬機中沒有安裝Adobe Reader，安裝後，妥妥的打開了。。。

//Tests specifically for Adobe Reader (aka Acrobat) in Internet Explorer
	var hasReaderActiveX = function (){

		var axObj = null;
		
		if (window.ActiveXObject) {
			
			axObj = new ActiveXObject("AcroPDF.PDF");
				
			//If "AcroPDF.PDF" didn't work, try "PDF.PdfCtrl"
			if(!axObj){
				axObj = new ActiveXObject("PDF.PdfCtrl");
			}
			
			//If either "AcroPDF.PDF" or "PDF.PdfCtrl" are found, return true
			if (axObj !== null) {
				return true;
			}
	
		}
		
		//If you got to this point, there's no ActiveXObject for PDFs
		return false;
		
	};
