Bootcamp touchpad drivers fail to install on Windows 8 RTM
I've just upgraded my bootcamp partition from Windows 7 to Windows 8 RTM on a MacBook Air (2011 Core i7) and have been utterly and entirely unable to get the touchpad to work.
Things I've tried:
- Uninstalling and re-installing the Bootcamp package
- Removing and adding the specific two touchpad devices in Device Manager
The touchpad worked correctly under Windows 7 and works under OSX, so this appears to be a Bootcamp/Windows8 issue, rather than a hardware problem.
Any solutions?
Go to Device Manager and uninstall (and delete drivers) for the two Trackpad devices then rescan for hardware. After which, then go find your Boot Camp drivers, and don't run the full setup, but instead find the folder that specifically has the driver install packages in them and install the ones that are along the lines of "Apple Multitouch Trackpad." After this, go to your Boot Camp options to make sure that it now sees your Trackpad. You should have full functionality restored after this.
Did get the answer from this forum post: How do I get my Macbook Pro trackpad working on Windows 8
Got my Apple Macbook Multitouch Trackpad drivers to install on 64 bit Windows 8 RTM.
Upgraded Windows 7 to Windows 8, keeping applications and files. As as result, Boot Camp 3.2 was already installed, but trackpad was not working.
Installing drivers manually using device manager from the Boot Camp 4 installation files failed. Windows compatibility mode failed. Hacking the BootCamp64.msi file using Orca to detect a different Windows version also failed.
So I went back to device manager which did not have any devices with problems, and I couldn't find the devices Apple Trackpad or Multitouch Trackpad. I tracked down two generic device entries called usb input device and figured out they were the trackpad installed with generic Microsoft drivers. When I tried to update these generic device drivers to the apple drivers, I got the error "system cannot find the path specified". Open up the system's SetupAPI log file and discovered the file not found error was caused by attempting to find driver files in DriverStore which did not exist:
C:\Windows\System32\DriverStore\FileRepository\applemtm64.inf_amd64_e9ad032101401c02 C:\Windows\System32\DriverStore\FileRepository\applemtp64.inf_amd64_e01424b60295b8a0
So I created those two folders and copied all of the *mtp64 and *mtm64 files from boot camp 4 installation files to these respective folders, and also copy the WdfCoInstaller01005.dll file into both folders.
After doing that I was able to use the device manager and install the apple trackpad drivers without any problems just by searching for the driver normally, and now my right click and two finger scrolling work great!
