The problem is that the Tomcat 5.5 and 6.0 installers are both using the same "display name" for the service ("Apache Tomcat"), and Windows doesn't allow that.
You can install the service correctly using service.bat in Tomcat's bin directory. 1. Install one version of Tomcat (let's say 5.5). The service should run correctly. 2. Install the other version of Tomcat (6.0). Ignore the error message about the service. 3. Open a command window and cd to the Tomcat 6.0 bin directory. Run "service.bat install Tomcat6". This will install the service with a different display name so it doesn't collide with the Tomcat 5.5 service. Note: service.bat might be missing if you installed Tomcat using the .exe installer. (I know some files are missing but I forget if service.bat is one of them.) If so, download the Tomcat .zip distro and copy the missing .bat files into your Tomcat's bin directory. -- Len On Fri, Jan 2, 2009 at 08:41, gen <g...@bud.co.jp> wrote: > Hi, > > > > The error windows shown as, > > > > Failed to install Tomcat5 service. > > Check your setting and permissions. > > Ignore and continue anyway (not recommended)? > > > > Thanks > > > > _____ > > From: gen [mailto:g...@bud.co.jp] > Sent: Friday, January 02, 2009 10:34 PM > To: 'Tomcat Users List' > Subject: RE: Is it possible to install both TOMCAT5.5 & TOMCAT6? > > > > Hi, > > > > I download apache-tomcat-5.5.27.exe and just run it. > > And it just gives me the following error window. > > # I already had Tomcat6 installed. > > > > > > > > Thanks > > > >> -----Original Message----- > >> From: Ken Bowen [mailto:kbo...@als.com] > >> Sent: Friday, January 02, 2009 10:22 PM > >> To: Tomcat Users List > >> Subject: Re: Is it possible to install both TOMCAT5.5 & TOMCAT6? > >> > >> How are you installing? > >> If you download the zip files for 5.5 and 6 from http://tomcat.apache.org/ > >> , and unzip them in separate folders, then > >> each can immediately be started directly using startup.bat in the bin > >> of the respective installations, and will run properly. > >> Dev environments such as Eclipse will support having multiple Tomcats > >> installed like this: after telling Eclipse about the > >> two installations, one simply chooses which to run from a menu. > >> > >> On Jan 2, 2009, at 7:57 AM, gen wrote: > >> > >> > > >> > Hi, > >> > > >> > I use Win XP professional.
