Your scenery.cfg has an error: the faulty line is probably related to the Hong Kong airport. The installer tries its best to defend itself from such errors, but of course it can't handle all possible cases.
Try to fix your scenery.cfg, by editing it, or delete the chek_Lap_Kok section entirely. Since the section is corrupted, FS9 is already ignoring it anyway.
It might be useful if you send me via email your scenery.cfg before modifications, so we can update the installer adding another possible case of corrupted file to handle.
