I have installed a freebee copy of Staroffice 7 and opted for it to operate only on Excel. I have decided I want to uninstall it but it has altered some Excel files. I have a copy of Staroffice 7 on a disk. The main file affected is a large spreadsheet. If I uninstall SO7 then there is no trace of the spreadsheet on the computer. If I reinstall SO7 then the spreadsheet is back in the condition I don't want. I have tried System Restore but that does no good. I did not backup before I installed SO7. How can I get rid of SO7 in the spreadsheet so thats its in the same condition that it was before I installed SO7, 6 weeks ago. I am using Windows XL.
