After downloading file dfsetup102.1.2D0D17.efw directly from the download link nothing happens. My computer says its some sort of email attachment which it still can't open. I'd appreciate any help.

Did you download from here arcy?

The download should be an .exe file.

Are you xp or vista?

Any other problems with .exe files?

Scans okay?

In order: Yes, No, XP, No, Yes.

Try the .exe association fix here

I solved it. I just changed the extension. Works fine.
