When booting the computer, it prompts with a message "LOSS OF pptool32Ex.dll" and it does not allow the penpower chinese writing program to load on.  

Here, can I ask any expert brother what to do for solving this problem.

I am using Windows 7 operating system.

Many thanks in advance.   

Dear fighterplane  brother,

Thank you so much for your prompt advice.

Will follow those mentioned steps to clear the problem.  Actually, I have emailed penpower technical support department  a week ago, but still haven't heard from them.
