thanks a lot for the link, unfortunately I already checed the registry key but I cannot import a word document into livecycle! I have the same error message that I mentioned, do you have more suggestions? Thanks a lot!
Not too sure on how to fix your error, but i do know that if you import a document from word and you try to edit it or add in certain things, its going to fail on you since the processes in the background of the word document(when imported, invisible and cant be seen(format etc)) will interfere. ie) expanding text wont work properly.
I really advise you making it from scratch on live cycle, it's pretty straight forward, and it'll waste less time
