des.dll missing file re installed no go

[SeeJay6969]

I had this software working great on 1.4d, of course when a new version came out I un installed and loaded the latest release. Now I get this des.dll missing file error need to re install. I have re installed till I am blue in the face, any ideas? I did a search and found this dll reference but not this exact message if this is a dupe post I apologize but I did try a search before posting.

download the setup package again, might be corrupted or make sure a firewall or spyware there doesnt think it is a bad-file (it could delete the file)
