When I want to install TeamViewer 10, why can't I select my system disk as the distination?

Seems it happened when I want to install other softwares before (but I can't remember which). I have a 128G SSD as the system disk, but it doesn't even appear as an option in the installer. How can I deal with this?

BTW. My SSD's name is Macintoch SSD, which is not appeared on the following window.

Translation of this window (according to my poor English, messages with en-US locale should be different):

Top: Installing "TeamViewer"

Left:

• Introduction


• Permission


• Target Volume


• Installation Type


• Installing


• Summary

Right:

• Please select the disk to install "TeamViewer".
  
  
  
  • GlacJAY: ...
  
  
  • Macintosh HD: ...
  
  
  • TeamViewer: ...
  
  
  
  


• "TeamViewer" can't be installed on this disk. It can only be installed on the disk running OS X.
