G'day all, I recently went from XP to Vista which has Office Excel 2007. The problem is that I saved spreadsheets from excel 2003 that saved as XLR files. The 2007 excel is supposed to open these files but it won't . There seems to be plenty of information on reading 2007 files with 2003 programs but not the reverse. Can I open them in a computer that has excel 2003 and save or convert the files to xlsx? Hope someone can help, old dog.
