@flopsy: I tested and it works fine for me here (and for @jonatack, thanks for confirming), so maybe your download was incomplete (you can check the rar file’s sha256sum is
11a9c199065c513a93c19269ffbb4bb094f8642a97686082e8cd2974673c599d) or you made a typo in the filename.
@jaylittle: you’re right, it’s “less than official” on purpose. Those files are simply not distributed by us. Legally speaking we can’t host the files ourselves, and we can’t distribute the files ourselves, without first signing some pretty strict OEM manufacturer/distributor license agreement with Intel (which prevents reverse engineering for example). Those unaffiliated third parties hosting those files are technically doing it illegally and Intel probably won’t care about them, but if a US-based business does that, then it’s a whole other story.
That’s the reason it’s done this way unfortunately, it’s less than perfect, but it works, until it doesn’t, then that gives us a little more work than usual, but that’s not such a bad trade-off.
