Hi,
I use Windows 7 Pro 64-bit running in Parallels Desktop 10 for Mac and using Microsoft Office 2013 64bit.
Now just installed 64-bit version of ESRI Maps for Office 3.0 and I can't log in to the ESRI maps in Microsoft Excel 2013 - The sign in window always loading. (See attached picture). But when I try to log in Microsoft Powerpoint 2013, it's worked.
Any thoughts on what's going on here?
Best,
Benny
