A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Just ran into this problem and fixed it this way:
- Logging on with Admin permissions (had to have HelpDesk do that).
- Repairing Office using the online option.
- Opening C:\Program Files\Microsoft Office 15\root\office15 and turning off (unchecking) all options on the Excel.exe Compatibility tab.
- Opening Excel Options > Advanced > General and unchecking Ignore other applications that use DDE.
Now files open without a problem from Windows Explorer.
