[otrs] Installation on Windows when Apache is already installed

[Gary Feldman]

I've searched the archives, and discovered that this question has been 
asked before but never answered:  How does one install OTRS if Apache 
(and other prerequisites) are already installed?

There's one note that's a couple of years old that claims it's not a 
problem, but when I run the 2.1.1 Windows installer, I get

    "Found the installed service Apache2.  Installation aborted.  Please 
remove the services
    Apache, MySQL, Perl, and Cron before continuing."

Obviously, removing such services is unacceptable, since the reason 
they're there is that other systems on the server rely on them.

Do the OTRS developers consider this a bug in the installer?  My opinion 
is yes; an installation kit could choose to require them as 
prerequisites, but it should never prohibit existing installations, and 
nor should it try to install them itself without going through the 
native installers for the various products.

Thanks,

Gary
