I have tried installing MikTex at least 6 times and I keep getting a "remote file not found" error for the file "miktex-urct-bin-x64.tar.lzma" during the download process. I'm trying to install the full 64 bit version using file setup-2.9.5721-x64.exe.
I'm using Chrome Version 45.0.2454.85 m and Windows 10. I did a reboot.
Here is a sample of sites reporting the file is missing.

setup-2.9.5721-x64.exe
has a bug.miktex-urct-bin-x64.tar.lzma
the installer tries to download does not exist on any mirror and I could fine no mention of in anywhere on the net either (though one CTAN report mentions it, it seems to have been out there once). I suppose there is some misplaced config file or other in the installer.
