You may find that the standard version of Tomcat will not run on a 64 bit server.

If you have difficulties, then please try the steps below:

- Download and unzip the standard core zip package (not the service version) from:
http://tomcat.apache.org/download-60.cgi

- Download the 64bit Tomcat exes from here (in the AMD 64bit directory):
http://svn.apache.org/viewvc/tomcat/tc6.0.x/tags/TOMCAT_6_0_16/res/procrun/

- Overwrite the existing exes in [tomcat]/bin from the extracted zip with those downloaded from the above link.

- Open the command prompt and navigate to [tomcat]/bin. Then run "service.bat install" to install the Tomcat service.

- You should now be able to start the Tomcat service.
