According to MSDN, value of dwLanguageId should be supported by the system. LANG_NEUTRAL, which is 0, seems like the right choice to me.

Also, mbp can be defined static to save some bytes as it'll be zeroed by default.

yes, those are good points.

for the languageid: i tried to set it with the chosen language of the installer but failed so far.
do you know how to do that?

i guess you can do those fixes for yourself, no need for a new patchfile ;)
