hello

     I performed the following steps in the non turnkey install of LiveCycle

     1) Installed the JDK 1.5.0_11

     2) Installed the Jobss 5.0

     3) Installed the Liveycle solution components

         I  get the following error on Application Server Configuration Details screen

               "Invalid server directory. Directory does not match expected valid application server install"

           Can someone please help ?

           Thanks in advance
