embed all fonts in eps

I have a lot of existing eps-files of which the option "embed all fonts" is unchecked.

Know I have to check the "embed all fonts" in the existing eps-files.

I tried to modify the script below, but it seems that the embedallfonts is NOT working.

When I do it manually (without script), then it works fine. With script, it doesn't work.

#target illustrator

// PART 1

var doc = app.activeDocument;

// PART 2 -> herbewaren eps als eps

var destFile = new File(decodeURI(doc.fullName).replace(/(?: \[Converted\])?\.eps$/, '.eps'));   // also remove "[Converted]" from filename

var options = new IllustratorSaveOptions({});   // new save as options

options.compatibility = Compatibility.ILLUSTRATOR15;   // save as CS5

options.embedICCProfile=true;

options.embedAllFonts=true;

options.pdfCompatible = true;

options.useCompression = true;

doc.saveAs(destFile,  options);  // save the file in the same foldere as the eps

// PART 3

doc.close(SaveOptions.SAVECHANGES);   // close the file with saving

Another question will be: can I get a dialog box to put in the path to the eps-files, I can do thereafter it in batch instead of each time opening and closing a file.
