I was actually pointing only to the failures in the test. These failures 
(varying number of failures per platform) happen on XP and below.

Unfortunately there isn't a 1 to 1 mapping between !IsValidCodePage() 
and E_INVALIDARG. (The exceptions are mentioned already in the test).

The ideal tests would then probably be something like:

ret = IsValidCodePage(i);
hr = IMultiLanguage2_IsCodePageInstallable(ml2, i);
ok((ret  && (hr == S_OK)) ||
    (!ret && (hr == E_INVALIDARG)),
    "Something wrong")

There are however numerous errors when running this on all platforms.
