To cmhsam,
You mentioned you're using a mac for cyberduck.
When you download the bluecop repo zipped file, did you do a RIGHT-click and choose 'download linked file'?? ...this will keep the file zipped.
If you click the zipped file directly, that's the problem...it's automatically unzipped if you click the zipped file directly.
When I right click and select download linked file it just downloads the .html file.
Is the zipped file ending in .zip.html?
If yes, just go ahead rename it from .zip.html to .zip (remove .html) - don't open it, keep it as zipped file...
