I ran into the same problem. Try saving the sheet in .xlsx. Close the file. Then rename the filename extension to .wks (you may need to uncheck "hide extensions for known file types" in explorer's folder options first). I was able to open the file in 2007 after receiving a warning. My company just migrated to Excel 2007. I ran into the same problem. Try saving the sheet in .xlsx. Close the file.

I have installed the fix, and it does work with 2003, but the difference is this: -In 2003 they disabled the format, and allowed you to re-enable it. -In 2007, they never included the code to convert the format. There is nothing to re-enable. So basically, if you need the wks (or other) formats, you are stuck on 2003 or earlier. Hi Jim,

Correct, the article only applies to 2003. I have installed the fix, and it does work with 2003, but the difference is this:

-In 2003 they disabled the format, and allowed you to re-enable it.

-In 2007, they never included the code to convert the format. There is nothing to re-enable.

So basically, if you need the wks (or other) formats, you are stuck on 2003 or earlier.

Microsoft has apparently labeled these file formats as insecure. The following list of the changes (blocked formats) is right from Microsoft's site: LotusandQuattroFiles .wk1, .wk4, .wj3, wk1 FMT, .wks, .wk3, wk3 FM3, .wj2, .wq1, .fm3, .wj1 DifandSylkFiles .dif, .slk FilesBeforePowerPoint97 This policy will prevent the saving of files that are older than PowerPoint 97 and that have file formats such as .ppt, .pot, .pps, and .ppa.
