System Requirements

As a web-based solution, OTRS Help Desk and OTRS ITSM can be flexibly installed on various platforms. The most common installations run on Linux and UNIX derivates, but you can also run your Help Desk or IT Service Management solution on a Microsoft Windows platform. The webserver and Perl have to be installed on the same machine as your OTRS. The database back-end can be installed locally or on another host.
