You can use "Auto CHDK to EXIF", update exiftool.exe to the latest version if does not work,or use DNG.Mod: link to site potentially hosting malware removed.
WARNING : when I clicked on download that site just attempted to load a virus / malware version of Adobe Acrobat Update by bringing up a bogus update window warning that my version of Adobe is out of date. This is a particularly nasty virus - it bypasses virus scanners with ease. I would not trust any file downloaded from that location!
@WW - any chance you clicked to one of those advertisements normaly shown under the Download button ?...my ADP kills those ads silently
