Did you install the program using wine? If not, you should do that really. If files are missing it might be a bug in the installer. If it still crashes after installation in wine you could put up a (bzipped2) debug log again somewhere, maybe i can make sense of something (btw run the app by WINEDEBUG=+relay,+seh,+tid WINEDLLOVERRIDES=winemenubuilder.exe=d wine appname.exe)
