--- Comment #19 from andy andy86@fastwebnet.it --- Hello. Make sure that all .dll, expecially mfplat that isn't included in Tony's script, are set as "native" in winecfg (or regedit), otherwise wine may follow up to use builtin instead. (place it in system32 may not be enought, you can use WINEDEBUG="+loaddll" to verify if dll is load as native or built-in)
You can send my an e-mail if you need help, consider I haven't RE7, but I can try to help you to understand if request .dll is correct loaded.
