I'm having trouble in opening .xlsx files created using excel 2007. File is on the sharepoint site (WSS 3.0). Since I have installled Office 2010 I am not being able to open this file directly from the browser. However, if I download it on my local PC its
seems to open fine.
Excel 2010 shows error "Excel cannot open file "filename" because the file extension or file format is not correct. Verify the file is not corrupted..."
Please can someone suggest what I am missing on my sharepoint site?
