I couldn't open it with any of my archiving software.......
That said - hey VH, you might want to mention in the first post that 7Zip is required for extracting your Windows pre-builts because not everyone recognizes it.
This may be the first how to open an archive question I've gotten. Note added.
cross-compiled cgminer.exe binaries (use
7zip or WinZip to open the archive)
