something needed

when i first use the software to read a pdf article,it prompts me that it needs setup tools(at that time i didnt take care of it) or else it will has problem to display.it aslo prompts me that i can get it from the site ,but i shut the prompt window,and also i forget the site and the tool needed.
when i use it to to the article again,the prompt window doesnt display.
when i read the article ,i find that the english word interlace the chinese words together,i think it is the problem once the prompt window prompted.
i want to know how to deal with it.
(now i dont know what is the tool i need,and where i can get it ,thank you for your replying.)

Do you mean the "Eastern Asian Language Support" ? This one you can download at www.foxitsoftware.com/pdf/rd_intro.php

When you will see the information again try to delete the Regestry entry from Foxit Reader.
But realize that your own settings will set to the defaults.
!!!Only delete this key when you know something about regestry!!!

HKEY_CURRENT_USER\Software\Foxit Software\Foxit Reader

The folder will be create new when you start foxit again.

yes ,the problem is just what you said.
i download the bin file ,thank you for your helping.
if i still have problem, i will be here too.
see you.
