My current PC configuration has Excel 2003 running within W7 apparently without problems despite the age difference. At some point in the past I downloaded Libre Office as a fallback. But if now I open an .xls spreadsheet from Windows Explorer it comes up within Libre Office. Clearly a case for manually changing the file association. But I don't seem to be able to find the location of my Excel 2003 to do this. Within All Programs this comes up just as
C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Microsoft Office
but this does not seem to correspond to the file structure within W Explorer.
How can I find where Excel program really hides?
