Word (version XP or onwards) could not be found on the machine

I am currently test driving LiveCycle Designer ES3. When I try to convert a Word document I get the error message "Word (version XP or onwards) could not be found on the machine".

- I have tried the registry hack posted by ES2 users on another forum. It did not work.

- I have tried converting both *.doc and *.docx; got the same error on both formats.

Is there a solution for ES3? We are considering buying the software but if we can't make it work with Word that would be a deal breaker.

My system:

- Windows Pro 64bit

- Office Pro 2010 64bit

- Creative Cloud (CS6 and Acrobat XI)

- LiveCycle Designer ES3 (trial)

Thanks in advance for any help fixing that bug!
