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?
Update: Our friends at DownloadSquad have a handy guide to making the ISO, in case you're interested -- and they say the installer does work in the end.
Update 2: We just got a tip that Microsoft is offering refunds to users who are having issues. [Thanks, Christopher]
