This one is a bit weird. If I run the installer to configure the demo in DosBox, it decompresses some of the audio files. When I played it back in ScummVM, the console started to display a series of warning messages about an audio file, and the program crashed after switching scenes. The demo plays fine and is stable if the installer is not used.
Please let us know what warnings were displayed.

This bug is invalid. The resource.aud is already unpacked, so when you use install.bat it unpacks the file again, leading to a corrupt file.
Sierra didn't make it check if the file was already decompressed before decompressing it again. Therefore you can continually use the file to "decompress" it.
