Had to share this find. Funny I have been to the site many times but never paid attention to this until now.
Question: Ever unzip a program and then promptly forget about it? I do! Sometimes I don't remember it until I just happen to run across it one day.
Answer: ZipInstaller
The ZipInstaller utility installs and uninstalls applications and utilities that do not provide an internal installation program. It automatically extracts all files from the Zip file, copies them to the destination folder you select, creates shortcuts in the start menu and in your desktop, and adds an uninstall module to allow you to automatically remove the software in the future.
