Trying to get Mac Keyboard volume keys working on Windows 10

I've done everything in the below text file. And when I open up Bootcamp from Control Panel I get this page. Not sure what to do next?

----

First of all boot in windows, then insert your Snow Leo disc.

Open a new window to explore disc content.

Go to Folder "Boot Camp" > "Drivers" > "Apple"

then copy "BootCamp.msi" or "BootCamp64.msi" to your desktop.

in the same folder copy the file "AppleKeyboardInstaller.exe" or take the one in "x64" folder if you're on x64 system.

When the two files are copied on your desktop you can eject the disk.

Then with an utility like Winrar or 7-Zip extract the "AppleKeyboardInstaller.exe" content.

When it's done run the file "DPInst.exe"

But the keyboard will work now.

After that, search you need to run "BootCamp.msi" as administrator.

To run "BootCamp.msi" as administrator, first of all, you need to open cmd as administrator ("start menu" > "all programs" > accessories > "command prompt" then right click "run as administrator")

In the command prompt, go to your desktop (cd /Users/*your users' name*/Desktop).

Then type "BootCamp.msi".

When the install is finish, reboot and it's ok!
