Recently I have had experience with a customer running Windows Vista on an Apple Macintosh computer. Quite interesting configuration setup and totally unsupported from Microsoft, and to be honest I have never seen so many errors and problems with hardware and drivers as with this machine. Anyway, trying to upgrade BootCamp to the latest version turned out to be a nightmare. Applying the latest BootCamp patch resulted in an instant error message: “Error applying transforms. Verify that the specified transform paths are valid”.
It didn’t take me long to figure out that this was caused by not using a system which is “all-American” but finding out exactly what to change took a bit longer. I soon learned that one have to edit the registry and making sure that the language code set there is changed to the US English code.
You do this by looking up the registry key HKEY_CLASSES_ROOT\Installera\Products \82654E0F812156845A61E8A84572A2CD and then changing the value of the REG_DWORD setting named “Language”. To be able to install Apple BootCamp update this setting must be 0x00000409 (1033).
