It used to be when I opened Windows File Explorer, I could double-click on a spreadsheet and Excel would be loaded and the spreadsheet opened. That action (for the past couple weeks) now results in Excel being loaded and the message 'There was a problem passing the command to the program.' I get the same behavior with Word.
In order to load the spreadsheet, I have to find it under 'Recent Items' or browse through Excel's Open Menu and double-click it.
The above is with my Desktop (with Win 7 & Office 2007). I get similar results on my Laptop (Win 10 & Office 2013), except that no message is displayed.
Has there been a change to Windows and/or Office such that this is now the correct behavior, or is there a Setting someplace that needs to get changed?
