I have MS Office 2007, Windows 7. When I double click on an xls file Excel opens up but it is just a empty excel program. It is similar to opening up excel and then just closing the book1 that opens up automatically. Just a grey background. Also I can’t open up xls files by doing File > Open or dragging xls files into an already opened excel. And double clicking an xls does not work. I tried doing a detect and repair on excel but that did not seem to fix anything. Any ideas? Thanks!
