--- Comment #7 from Sven Baars  ---
I still haven't figured out the exact implementation, but I found at least one
issue with the current implementation.

if (CreateProcessA( "C:\windows\syswow64\msinfo32.exe", NULL, NULL,
NULL,
                        FALSE, 0, NULL, NULL, &si, &pi ))
    {
        [get the env from pi]
        query_env_var(env, L"PROCESSOR_ARCHITECTURE", is_win64 ? L"AMD64" :
L"x86");
        query_env_var(env, L"PROCESSOR_ARCHITEW6432", is_win64 ? NULL :
L"AMD64");
    }

The above test works for me on windows but fails for me on wine. The exact
issue with this application is a bit different, but it's similar in the sense
that the native machine is not reported where it should be.

Putting back the old code, but replacing

RtlInitUnicodeString( &nameW, L"x86" );
        RtlSetEnvironmentVariable( env, &arch_strW, &nameW );

with
        RtlSetEnvironmentVariable( env, &arch_strW, get_machine_name( machine,
&nameW ));

fixes the application and the above test.
