You should search through the list archives, e.g. at Nabble.com. In this list there were several reports of successfully running Tomcat on 64-bit Windows during the last 6 months. Though that required some manual configuration or tweaks.
Have a look at 1) http://www.nabble.com/Installing-Tomcat-on-Windows-Server-2003-x64-td10294769.html#a10301090 2) http://www.nabble.com/Advice-about-Tomcat-on-x86_64-architecture..-td11500727.html#a13279694 I suggest you to 1) make sure that Java itself is running correctly for this OS and hardware, 2) start Tomcat from *.bat files (look into zip distributive, as those are not included with exe installer) to make sure that it can run on pure java, If 1) or 2) fail, it is Java / OS / configuration issue. 3) only if steps 1) and 2) show correct results, proceed with installing 64 bit versions of service executables, as suggested in reply by Mark Thomas. --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
