Instead, I don't see any of the drivers that Boot Camp said it was installing. Again, I would expect the Device Manager to look as it does in the previous link. The Device Manager still shows the default drivers for devices such as the keyboard. Based on this link which describes a typical Boot Camp install in Windows, I would expect the Control Panel to have tabs such as Keyboard, Trackpad, etc. The Boot Camp Control Panel has only one tab, "Startup Disk". However, I've noticed a number of things that suggests the drivers didn't install properly. The install seems to have partly worked - for example, the LED keyboard was dark before and now it is lit up, and a taskbar notification icon was added that says "ENG" and indicates I'm using an Apple keyboard. This launched the Boot Camp install process, which appeared to install the Boot Camp drivers with no problems. As described here, I opened an elevated command prompt and navigated to the BootCamp\Drivers\Apple folder and ran "msiexec /i BootCamp.msi". From my research, this often happens when trying to install Boot Camp in Windows. Boot Camp 圆4 is unsupported on this computer model". I was not able to run Boot Camp setup directly. I downloaded Boot Camp Support Software and extracted the contents. I don't need Boot Camp to help me boot, I just need the drivers to get things like the keyboard, trackpad, and wifi adapter functioning properly. However, I can't seem to get the Boot Camp drivers to install properly. I'm not having any problems in booting Windows 8 or using it. Everything seems to be working fine: display, ethernet and wireless, sound, track pad, eject button all function perfectly, but the ! in Device Manager are driving me crazy.I have a MacBook Air 2013 that does not have MacOS installed, but is booting Windows 8 Pro 64-bit (clean install, not upgraded from Windows 7) in a vhdx file via EFI. I've installed Windows 7 on 10+ Macbook Pros and never once run into missing drivers after installing the boot camp driver pack. I found several references to the missing Coprocessor and SMBus online, but the posted solutions (to install nVidia drivers, to run the Intel Update service, to let Windows 7 try to find the drivers itself) all failed (some of the driver installations reported the incorrect hardware, some installed but didn't resolve the missing drivers in Devmgmt).

Lo and behold, 3 drivers were missing: Coprocessor, SMBus, and a third that I can't recall at the moment.

I then restarted as normal and went about the myriad other installs, when I entered devices and noticed the "!" symbol on the computer. I installed Windows 7 on a user's Macbook Pro yesterday (Aug 2010 model I believe) using Boot Camp, then I used the Mac OS X disc to run the Boot Camp Drivers installation.
