Vista Doesn't Allow QuickTime Updates

I was having problems trying to update QuickTime on my laptop with Vista. Two different laptops, in fact. It would go all the way through the download, click on the UAC to allow the install but then it would fail. No real clue as to why (one of those wonderful non-specific error messages). After much searching through different engines (Live, Google, Yahoo), I started to see some other blogs refering back to this one site. Turns out it's a problem with VBscript being registered properly on Vista. This was not anything related to the error message I was getting, but it did fix it!
