I get this (SEE SCRIPT AT FOOT OF MESSAGE), but in a different spot every time. not sticking only at the same point, but rapidly after the install begins

i have closed everything, turned the computer off and unplugged it to rest it.

when it wouldn't dwonload in the first place, i deleted everything unnecessary, and then tried again. no luck. then i uninstalled minecraft using the installer, and then tried again fresh.

i am more upset now, because i have no version of minecraft at all to play. my son paid for this new version only because after months and months of trying to get our mojang account details, he tired of waiting and brought minecraft again, so we still had the original version to play. now, we dont have that, we dont have anything, and tyhe new one will not install. i have plenty of power, plenty of space, plenty of ram, so, i am befuddled.

PLEASE HELP ME!!
