I have a new copy of MS Office 2010 Professional. I have no problem with Word documents. When I try to open an Excel file (or Powerpoint for that matter), the document looks like it's associated with Excel, but when I click on it I get an error message: "...is not a valid Win32 application". If I open Excel and then ask to open that file, the file opens just fine. I've used the Open With command and tried to navigate to the Excel executable, but the only thing that comes up in a search is "Microsoft Office 2010 Component" with the Excel logo. And that won't open the file. The only thing that seems to be visible on my file system anywhere is that "Component" or the shortcut available under "Start / Programs". There must be something somewhere else I can point to.



Thanks in advance.
