“This Font Pack, which supports Chinese Simplified, can be installed either on demand or as a standalone installer. "On demand" means that Reader realizes it is missing the Font Pack needed to display or interact with the document and asks the user if the Font Pack should be downloaded and installed. A standalone installer, which you can download from this page, allows the Font Pack to be installed independently of Reader.”
