Not working for many , Windows 7 student upgrade installer

The Windows 7 launch seems to have gone off mostly roses and sunbeams, but we're hearing today that quite a few people have had issues installing the downloadable $29 student upgrade edition on 32-bit Vista -- apparently the file doesn't unpack to an ISO, but instead to an executable and two bundles that don't function properly,

and eventually the process errors out with a 64-bit app trying to launch on 32-bit systems. It's possible to create an ISO using some hackery, but the install process seems to be 50/50 after that -- we've heard of both success and further crashes. For it's part, Microsoft says it's looking into things, so hopefully a newly repackaged download will be forthcoming -- every party has its ups and downs, right?
