I don't have the option to unpack the files or folders.

I don't have the option to unpack the files or folders. I can zip files very well by using send to > folder compressed... no problem. It gives the file compressed Photoshop icon for some reason any. I tried to change the association, but not luck.   I don't have WinZip or anything as it is installed. Help!

original title: cannot unzip in Vista

Looks like the registry entries for the files ZIP is confused. These must be the default values:
