Hello. I'm creating a program and I'm trying to add context menu support to it. What I need to be able to do is when users right-click on a ZIP file, they can choose "Install With GMI" (my program). I know you edit the Classes Root section of the registry. However, I'm not sure what keys to edit. Also, which keys do I create? Do I edit the ".zip" section? If so, what keys do I make? If someone could help me with this that would be extremely helpful. I couldn't seem to find anything on the internet that worked.

Should you be doing it in this mannor ? ADDING TO RIGHT CLICK MENU: Control Panel> Tools> Folder Options> File types tab> (find and single click ZIP file)> Advanced> Then in actions list add or change what you want.

That would work, but I would need to be able to do it by editing the registry. The installer for my program will need to be able to add the entry in the context menu, which means it would need to be able to edit the registry. Do you happen to know how to do that through editing the registry?
