Install Pdf Generator

Hello,

I would like to use a software to encrypt documents on a server. Documents must be decrypted by users on their computers.

I think Pdf Generator is the best way to do that, but i encounter some problems during LiveCycle ES 2 install.

1- Do I really need  LiveCycle ES 2 to use Pdf Generator? Is there a standalone version of Pdf Generator?

2- Is it really the best way to encrypt pdf documents?

Thank you,

Regards
