Please disregard my earlier post; I just noticed that there is no full installer for the traditional Chinese Reader version (only 10.1).
All I can suggest that you reinstall version 10.1 and disable auto-update for now.
It could be a case of a corrupt installation which could be causing the crash.
Could you please follow, ʇɐb ɹəuəllıʍ suggestion, and uninstall the current installation of Adobe Reader 10.1.2 and restart if prompted for.
Try and install Reader 10.1.0 again (from ftp://ftp.adobe.com/pub/adobe/reader/win/10.x/10.1.0/zh_CN/AdbeRdr1010_zh_CN.msi).
Now update the same to 10.1.2 using the installer from http://ardownload.adobe.com/pub/adobe/reader/win/10.x/10.1.2/misc/AdbeRdr1012.msp
Try and launch Adobe Reader post the successful installation.
Do ensure not to launch the application during the updating process.
Hopefully this should fix things.
