Hi,
it's a problem of Excel and internet connection from plugin level. Microsoft has messed something up.
The workaround is to do a data upload to the "DATA" ribbon. Load anything as an import of an xls file (such as the example file provided by MS chicago crimes.xls). Once the data is loaded, the ribbon and the 3d Map button works.
You can see the problem on the green line at the very bottom of Excel. If you don't load the data, there is a "no connection" message, as you load the data, "done" appears.
Someone needs to explain what are the mechanics of excel connection and how to diagnose or regulate that it is online or offline.
