Hello,
I cannot use the Windows installer because I've already an Apache server and MySQL running on the same box where I need to install OTRS.
Sure you can. The installer lets you choose which components to install or not install. Run the installer but leave out the mysql piece. Install everything else. The apache piece wont' hurt anything because it is not started by default. Nothing else should interfere either because the Windows installer places everything inside of a main directory "otrs". Your tree structure will look something like this: Otrs # root directory apache mercury mail filezilla .... otrs # this is the main otrs directory .... .... Once it is all installed you can then go into the apache httpd.conf, specify a different port to run under, and then fire it up. Windows will run two different apache servers just fine. When you look at Apache Monitor it will show two instances going. If you don't want to go this way, then just copy the relevant sections of httpd.conf into your existing apache config and then you can delete the apache folder in the OTRS installation. Once you are all set with the webserver, run the installer.pl and point your script to your existing database. You should be all set. This how I setup OTRS even though I had an already existing apache/mysql installation. Hth, Tyler Hepworth
