If you have an existing installation of Corticon Server and subsequently install Rollbase on the same machine, you may run into a conflict when starting Corticon Server. The shortcut that launches Corticon Server doesn't work and seems to start Rollbase instead. To solve this issue, do the following: open up an empty DOS CMD Window and type:
Echo %CATALINA_HOME%
If you get a response that points to your Rollbase instance, then that is the problem. The Corticon Server startup script looks for the existence of this variable and starts up the Tomcat instance that lives there. If it doesn’t exist, the scripts just use the directory you are in. The solution is simple: delete the CATALINA_HOME environment variable on your machine.
