I have had hassles installing windows live suite, especially at work. If your Windows Live installation does not start or the installation program stops responding (hangs) and does not finish then what do you do?

There could be number of reasons as listed in the KB 940065. It has also listed steps to correct them. If all fails, uninstall windows live services. They have a download package, which will uninstall windows live services.
