Perl script displayed as text in Pipeline Pilot result

Hi,

Installed Pipeline Pilot Client 9.5 last week (as part of DS4.5). Works fine, however, 1 annoying problem arises. 

When running a sample protocol, such as "Predict Sequence Properties", the hyperlinks in the resultfile link to a perl script that is than displayed as text. I know it should be able to run as script, instead of displayed as text, but where to start? I tried the httpd.conf file(s) found in  .../apps/scitegic/core/packages_linux64/apache/httpd-2.2.22, but no success yet.
Some hints are appreciated.

Kind regards
