I haven't checked the MD5 hash file, however the "official" torrent file from http://www.linuxmint.com/edition.php?id=83
doesn't include it (includes MD5 but not Mint4Win).
I did a recheck on the torrent and it came up 100%.
There were two files called mint4win both were 1KB ( 1 was an .ico file and the other was just shown under Windoze as a "file" not an .exe and what programme would you like to open it with?.
On the mirror site the Mint4win.exe file was as large as life and very easily accesible.
Both sets of .isos were mounted using Daemon Tools Lite (latest) on Win 7 x64 Ultimate (fully patched).
Trrent client was Utorrent 1.8.3 (its not the latest but it is the last Utor to work nicely with the XBTT tracker).
