Stuck at 0%

I have seen previous threads on this - but none that are recent with the 4.02. I have tried unmounting and re downloading everything. I have tried multiple memory sticks as well as CF cards in readers. Any suggestions? It is just hung there and looks like it is waiting on something - but I am lost.
thank you

I have exactly the same problem, can anybody help? I am using the Mac version of the installer by the way …
All the best

You may try using an alternate flash drive.
