They build when you first run cgminer. If you haven't ran a new version of cgminer yet, you won't have a .bin file yet.
Anyway, you want to run cgminer the first time with the 2.5 sdk .dlls in the folders.
After you do that, you can replace the 2.5 sdk .dlls with 2.6, but cgminer will run as if you still have the 2.5.
What .bin file, There isnt, And has never been one
In the cgminer folder.
See the .bin files?
PFFFFFFFFFAHAHAHAHHAHAHHAA
