I have a calendar list with attachments enabled. When i attach an XLS file to an event, SharePoint wants to open it in xlviewer.aspx, but throws an error every time. I don't want to open the file in a browser. I just want to download the file directly. How can i disable the xlviewer?
The problem is similar to the problem described here, except that these affect attachments, not a document library. The list does not have a "browser" setting that i can see. The file handling in the application is set to "permissive."
