Sorry, the installer could not install Maintenance (Error 9.100)

Was working fine for the first two or three installs but now fails on EVERY BOX I TRY.

I have tried everything: Homesharing, no homesharing, Airplay> play song while installing, nope, NOTHING works. Has anyone come up with a fix for this? How can I bypass ATV Flash and get XBMC/NitoTV without it?


Thanks in advance – very frustrated.
