It might be the RM__ version your using - Japanese translation, English, help files and whatever not being in English or whatever.
Yeah sorry I actually meant to include that in there I am using rm2k3 version 1.08, translated by RPG Advocate. and my help file is in english as well.
Unfortunately I haven't a clue how to help. Sorry, mate.
YEah I was just searching google and all I could find was people acknowledging the fact that it happens but not what to do about it or what the damned check boxes are asking. I did come across an entry in wich bluecube himself even noted on the problem but from what I can tell he cant even fix it, or at least not at the time.
Errors, I don't know about (other than the "folder does not exist, create it?" box, but that one is obvious enough), but the first checkbox is for adding a shortcut to the start menu, and the second checkbox is for an uninstaller. Everything else is pretty easy to figure out.
Can't be fixed as far as I know. I can edit some parts of the dialog in reshack but that's about it.
