Joel Amar discovered that on new iMacs and MacBook Pros, he could no longer install Boot Camp drivers in Hebrew and Arabic versions for Windows. He found the cause of the problem, and a solution:
Since the last iMac models (21.5" & 27") and the new MacBook Pro (i5 and i7) it is not possible to install Boot Camp drivers on Hebrew or Arabic User Interface Localized version of Windows (XP, Vista or 7) and probably on many other localized versions.
No error message or indication appears during installation, but after restart only the Boot Camp control panel and HFS drivers are installed. Missing are all the Apple drivers (Bluetooth, iSight, Keyboard, etc..), Cirrus, Intel, Broadcom, Atheros drivers.
Trying to manually install the drivers from the driver folder results in this message: "The installer does not support the installed language." In the past there were no restriction or technical problem to install Boot Camp Drivers on localized version of Windows.
The cause is in a change introduced in the DPINST XML descriptor file present in all the drivers, the file is responsible for installation policy and for displaying the EULA in the proper language.
When no corresponding language is found, usually the installation is possible thanks to the line: "<enableNotListedLanguages/>"
Since the last models, this line is omitted and it is not possible anymore to install the Boot Camp drivers and results in a non-functioning Mac. This line was present on all Boot Camp drivers until now.
The listed languages are: Chinese, Japanese, Korean, Danish, Dutch, Norvegian, Swedish, English, Finnish, French, German, Italian, Polish, Spanish, Portugese, Russian.
Other languages including Arabic and Hebrew UI are completely ignored and banned from Boot Camp driver installation and there is no logical reason why Apple is preventing us to install Boot Camp other UI.
The only fix is to open each driver with winrar and add the line <enableNotListedLanguages/> in the DPINST file.
We note that you need to include the angle brackes, and to add the line at the beginning of the file, under the line <dpinst>.
