Windows 7, Office 2010
Recently upgraded from Office 2007 to 2010. We have a number of files on our system that are Excel files, but they do not have the XLS or XLSX extents (a process that makes a backup copy appends a timestamp to the copy when moving, so they are named something like filename.xls_201203021154).
When Office 2007 was installed, from Windows Explorer we could right-click the file, go to Open With, and Excel showed up as one of the options. After the 2010 upgrade, it no longer is provided as one of the options. However, Word 2010 is shown in the list, along with many other things we've installed like Adobe Reader).
I don't know why Excel disappeared from these options. The files open just fine from within Excel's file open dialog. So, at least I have this workaround but I would like to reactivate the convenience of being able to open them from Windows Explorer.
So, is there something I can do get Excel to show up in the list of programs when "Open With" is selected? As you can see, the extent of the file is going to vary on every file so I can't create a file association.
I thought it might be some sort of extra protection that MS was imposing, but Word does show up in the list so not sure what is going on there.
