Sounds like the file associations may have got a bit messed up when you did the 2010 un-install. You need to reset the associations

You can do this by starting Excel from the Run dialog box on the Windows Start menu using the /regserver switch.

Open the Run dialog, then enter Excel.exe /regserver and click OK.

This causes Excel to set itself back to "factory defaults".

You may need to include the entire path to Excel: "C:\Program Files\Microsoft Office\Office12\Excel.exe" /regserver

Of course, change the path to the correct value on your machine
