I have checked your demo site http://www.ocxt.com/officeviewer.htm, for displaying the office files (pdf,doc,xls,ppt,xlsx,docx) in the IE Browser for our web project Implementation.

It’s perfectly displaying all the file types of MS office in IE browser in Document Mode: Quirks only, but for other types of Document Mode (IE 7 Standards, IE 8 Standards, IE 9 Standards)

Your site is not working/displaying the MS office files in the IE browser.

Please give me yours feedback for this issue as soon as possible.

we need to open MS office files in all the types of IE Document mode (IE 7 Standards, IE 8 Standards, IE 9 Standards)
