Unable to open xlsx in Excel 2007

Good Afternoon

Yesterday I uninstalled Office 2000 and Outlook 2003, and replaced it with Office 2007 Professional.

Today, I am trying to open a .xlsx file but am unable to do so from outside Excel.

If I open Excel, file open, then I can sucessfully open the file.

But xlsx is associated with Microsoft Word in the Vista/Default Programs screen. It will not allow me to change the program to Excel because every time I browse to EXCEL.EXE it just comes up with Microsoft Word as the default program.


Has anyone seen this before?

One thing I will add is that Office 2007 is fully patched but not yet activated as I am still waiting on microsoft to release the license key to me (hopefully today they will finally do so!).



Hi Sachin :)

After reinstalling for the 3rd time, running CCleaner to clean the registry..............it now works.

I am now able to successfully open .xlsx files from email attachments (ie from OUTSIDE of Excel) with no difficulty.

Thank you for your weblink, but the 3rd reinstall has resolved the fault.
