Adobe Reader X Japanese font problem in Windows 7

This is happening if we open a PDF with Japanese font in Windows7 OS.

Tried to install Japanese font pack for Japanese Adobe X. But that is not getting installed with an error message : 'Install Adobe X before installing Japanese font pack'.

Only fontpacks for 10.1 version could get installed successfully. But its again same issue.

Can anyone hele here?

Thanks,

Rashmi
