.xls files not displaying evaluation edition

Me again!


I am currently playing with the ASP.NET_MVC_Front_End example from github and have encountered a problem.

.xls / .xlsx files just do not appear at all and I receive the attached error. The file is not set to read only or anything like that so I am wondering where the permission is set?

Any ideas where I am going wrong?

I am using attempting to view using the html rendering mode.



I cannot send you the .xlsx file due to the attached issue : )



This document does not show in all browsers but only IE 11 causes the breaking.
