This is not a complete how-to, because I do not think its warranted…you pretty much click Next Next Next (which in itself is a credit to the product)
But one thing to note – on the few machines I’ve installed it on, the installer gets to 100% and then just sits there for a LONG time.
If you click on the "Details" button, you’ll see the location of the installer log. The long pause is in the "Saving Inventory" phase…
So my advice is – just be patient. It will (eventually) get to the "Installation finished" message 🙂
