------- Additional Comments From dank@kegel.com 2007-20-04 13:57 ------- The setup.log file created by the installer says
[ResponseResult] ResultCode=0
which according to http://helpnet.installshield.com/robo/projects/helplibdevstudio9/SetupLog.ht... means success. So for now you should probably ignore the win32 exit status from setup.exe, and just use that log file's value instead.
