That's the error I get after installing the Windows Legacy Updater thingy and double clicking on the WLU file. Granted, I've got like 5 gigs free, so I'm pretty sure it's not that. I tried everything, like reinstalling the OS, reinstalling the Updater, installing the IE6 update some threads mentioned, running as Administrator, yet I still get that EXTREMELY unhelpful error. Anything I might be missing here? Using version 31IM in case that helps.
