Something in ThinkFree Office gets deleted?

Hello,

I have ThinkFree Office. Lately, it is the only program that has been demonstrating an inconvenience. Every time that I turn my computer on, I have to reinstall it; consequently, it works quite well. The inconvenience occurs when I restart or turn my computer off. To my judgement, following my anteriorly mentioned action, something in the program gets corrupted or deleted. I don't know the provenance of the inconvenience, but it is bothering me.


Salutations.
