They're bbbbbbbbaaaaaaaaaaacccccccccckkkkkkkkkkkkkkkkkkk. After some incantations, Ouija boarding and me dancing around a build server with a spindle of DVDs on my head and sacrificing a serial port mouse, the fixed 1.7 coinstallers are available.
Sorry for the delay and the initial issue... The 18002 build of the WDK should be out shortly (about a month...or so) which will have all the WDF redistributables back in their original homes.
Thanks for your support.
