Can use adobe livecycle reader extensions es to compile adobe livecycle designer ES3 file?

Hi ,

I am using livecycle designer ES and livecycle reader extensions es to create some PDF files. I want to use the new feature action builder, so I downloaded the designer ES3. After creating some new files, I tried to use livecycle reader extensions es (old version) to convert the file to add the saving function to adobe reader. It could not convert the file successfully and stuck at downloading the file page as the attached screen. Does that mean I have to upgrade livecycle reader extensions es to es3? Thanks in advance.

Regards,

Craig
