Penguinisto, thank you for the useful information.

Quote - I'd say, if you changed only the OBJ, then encode that. If there are several files that need encoding, it's easier to Zip them up and encode the result: but remember to leave your readme unencoded so folks will know what to do. :)

Good points. Just realized I have a bunch of files that relates to my product so it will be better encoding the whole bunch.

I first made an .exe file (installer) cause I figured it be easier on the user but CP (Content Paradise) prefer use of  zip files.

kaveman, very good suggestions. I have made "step by step" instructions with images to show how to go about. I know by experience how impossible it can be when there are no instructions.

So to sum it up (just so I have my thoughts straight around this), the product files are zipped then encoded, then the encoded file and instructions docs are zipped and that zip is the download file.
And this will work for both PC and Mac.
