I recently upgraded to 10.5.1 from 10.3.1 and have noticed that I can no longer drag and drop an XLS table into ArcMap 10.5.1 like I was able to do in 10.3.1. I get a "Failed to connect..." message, as illustrated below. But I can drag and drop an XLSX, but I have to open the XLS in Excel first and save it as an XLSX...a bit inconvenient.
Is that a bug, or do I have a dodgy install of 10.5.1, or do I need to make a setting somewhere to be able to drag and drop and XLS, or is that just the way it is?
Thanks.
