Microsoft Office Questions and Answers - How to Make One Version of Excel Your Default When You Have Two Installed
Dave writes in with an Office question Question:I have 2 versions of excel on my computer and want to change which one is the default when opening and spreadsheet. How do I do that?
Answer: I would right click on any Excel file and choose Open With and if the version of Excel you want to use as the default is not listed then click on Browse. Then find the Excel.exe file that goes with the version you want to use. It should be located in something similar to C:\Program Files\Microsoft Office\OFFICE11 (for Excel 2003) or C:\Program Files\Microsoft Office\Office12 (for Excel 2007) etc. That should set the file association for Excel files.
If you only use one version of Excel then you can also uninstall the other version.
