Hi Daniel,
You may have a typo with the picking up of the agent profile file so the Tomcat java process cannot find it i.e. you have an extra ":" after the "=" so "=:<path>" should be "=<path>".
If you installed the agent into directory D:\CA\introscope9.7.1\wily\ you should be using something like:
-javaagent:D:\CA\introscope9.7.1\wily\Agent.jar -Dcom.wily.introscope.agentProfile=D:\CA\introscope9.7.1\wily\core\config\IntroscopeAgent.profile
If that does not resolve the problem please see this related thread for other advice:
Configuring the Java Agent for Tomcat
Hope that helps. If not please let us know.
Regards,
Lynn
