Trying to install the Lifecycle ES trial....Followed the recommendation to install Acrobat 9 Pro extended first... this worked...
Installing the Workbench produces the following error. This is after putting in the serial number...and the installer having produced an installshield dialog box with command line options, and having pressed next on the release notes agreement..
(Aug 7, 2008 10:18:52 AM), Install, com.adobe.installshieldx.installer.wizard.DesignerProductAction, err, An error occurred and product installation failed. Look at the log file J:\Program Files\Adobe\LiveCycle ES\Workbench ES\log.txt for details.
I am facing the same problem. I have ensured that I have followed all the steps given in the installation mannual. This clearly indicates there is some thing wrong with the workbench installble (trail version). I do not know is it by design (intentionally done by Adobe it self). If it is so, its shame on Adobe.
