Adobe Security Updates for RH 8

Hello,

I wanted to update my RoboHelp 8 with the Security Update mentioned in here. Though its an old post, I need to update the same in my machine. The link to the zip file (APSB11-23_2.zip​) is broken (404 error).

Can someone tell me where can I find and download this zip file? Need it urgently.

Thanks in advance,
