external_task or cgi_task?

andrew_yeo

i wish to excute a Perl script after certain Task Transition within a workflow. Should i use CGI-Task or External Task?

I tried both, it just stalled at the task. I checked the iwjoberrors.log, it says
"Could not run c:\iw-home\local\bin\whatsnew_indexer\GenerateIndex.ipl for task 115356; aborting (requires admin attention)"

What does it mean??? I tried the cmd offline and it works fine...
