Dave's new puppet is not working

Just FYI, these are community forums. Fellow community members helping each other. There is a separate are to submit support requests that is manned by Adobe staff (although they also frequent these forums).

What I suspect is the file you downloaded had a .puppet file extension? If so, yes, it is a ZIP file, but you are not meant to open it up. You go into a CH project and use “Import Puppet” from the menu and point it at the *.puppet file. This will add the puppet to your project.  That is, CH reads the ZIP file for you and pulls out what it needs.

There may be other ways to load it, but that is what I do.

The chproj files are zero length. When you double click on the file for a project (not a puppet) it starts up CH. It then uses the directory the chproj file is in to work out where the rest of the project is. But it is a little confusing that puppets also contain this same file. So I am not 100% sure you downloaded a puppet or a project - but from your description it is a puppet in which case don’t extract the files in it.
