Error installing Key Agent drivers in Windows 7


i reinstalled fresh bootcamp (windows 7 x64) on imac running yosemite. i'm having difficulty installing drivers, had first bypass issue x64bit drivers running through cmd admin errors

"service 'key agent/mac hal' (keyagent/machaldrivers) failed start. verify have sufficient privileges start system services."

have tried following instructions seemed answer this:

i had exact same problem, on 17" mbp. in case, win7 event manager reported bootcamp 3.2 services failed install, in particular keyagent service (and without no apple keyboard , functions , apparently bootcamp icon doesn't show in system tray).

event manager said bootcamp installer did not have sufficient permissions, went dial down user account control (uac) settings (in fact, turned off). should have seen when bootcamp 3.2 update running window ask permission continue (allow software install). instead, there silent failure.

ok, turning off uac gives permission in advance (you have reboot after changing uac settings in order ensure off). after rebooting, went programs , features , found bootcamp services software item. selected "repair" , after reboot, in business! keyboard fine (including disk eject button, wanted working). went turn on uac default level (one notch below highest setting). useful (normally) have on.

ask windows system if don't know how find uac settings give try. hope helps you.


have followed these instructions, tried on different uac settings, (including resets) , running repairs on program in programs , features , rerunning in cmd same evil error keeps getting in way.

had , solved issue recently? can install these drivers way?

regards.
 

you're attempting install old driver set. 3.2 designed windows xp , has long since been superseded version 5.0. if imac older, boot camp 4 drivers should work. driver packages available on apple's support website.
