Export report, but Excel doesn't open. The process worked perfectly until Security Update for Microsoft Excel 2013 (KB3115262) 32-Bit Edition was pushed.

Update for Microsoft Excel 2013 (KB3115262) 32-Bit Edition


Sustaining Engineering research indicates that KB 3115262 is going to break pretty much any application that generates Excel files, Web Viewer included.

- This is Microsoft's work-around (until they fix it)...


- A better way of addressing the problem is to un-install the Excel update and prevent it from being installed.

Additional Information:

CA cannot fix this from Web Viewer. The Excel files it generates are actually HTML files (that follow special rules) with an XLS file extension - KB 3115262 now blocks this kind of content.
