This can be caused by a couple of things.
My main suggestion for fixing this is to:

• Right click on the file you want to open, ie. "File.xlsx"
• Select "Open With..."
• Click on "Choose Program..."
• Click on "Microsoft Office Excel"
  (If you do not see this option, click Browse, then locate "EXCEL.EXE" (Under C:\Program Files x86\Microsoft Office\Office12\excel.exe"))
• Check mark "Always use the selected program to open this type of file"
• Click on "Ok"

If this is 32Bit windows you may not have a "Program Files x86" folder, so just replace that with "Program Files"

This should work to open those files from now on. However this could be a more serious problem, and you may want to get someone to look at your computer if you are not experienced with problems like this.

Run a repair on the Office 2010 installation from Add/Remove programs.

This issue results from having multiple Office installations, as documented here.
