Evening2? I looked a bit, can't find any such file in MY RTP, so I'm not sure where you're getting that.

Of course, that's probably an RPG Maker 2000 Panorama file (that sounds familiar). Which means that your installer is corrupted. I suggest you do one of the following:

1) Find/Download RM2k3 instead.
2) Skip the installation of that file, if possible.
3) Download the RM2k installer somewhere else.
