I'm getting the same problem... when you click on the link to download limewire from their site, a web page is prsented with a quicktime logo displayed whilst the install exe file is being down loaded.
once the exe file is downloaded the QT logo changes into a QT Movie logo and a message is then displayed
'QuickTime is missing software that required to performe this operation. Unfortunatly, it is not available on the QuickTime server.'
it doesn't tell you what program is missing, where you can get it from or what to do to resolve the problem.
i am running windows ME and have reinstalled QT and this has not resolver the problem, please help...
