I have a problem opening the new Excel format (.xlsx) in Excel 2003. It seems as though the compatibility pack will not convert the file. I have checked Word to see if it converts .docx which it does so the compatibility pack works there.
What I have done:
Re-installed the compatibility pack twice
Ran Windows update on the machine
Checked for other versions of office
Tried different .xlsx files
I don’t know what else to try, I have looked the problem up and found a thread which suggests the above fixes. The only other thing I can think of is a re-install of office but this is something I would like to avoid for the time being.
Thank you for any help
