Hi 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? Bhavesh

Which OS are you running on your workstation? And, what version of Internet explorer? Do you want it to open the file in Excel or do you want to be able to view it embedded in the browser session? Cheers, Lewis_Carroll

I am using windows server 2008 and Sharepoint 2007. The IE version is IE8
