Liveinstyler update-notify is a simple tool to let users of your product know when an update of your product is available. It also works simple: This tool will create a small file containing the actual version of your product which has to be distributed with your product. The Update.liu file contains information about your program and the version the user has installed. When a new version has been released then the Update.exe application can compare the installed version number (in update.liu) with the new (latest) version number in the file posted on the web.
