Resolution

To force the agent to look in the .Net agent installation folder modify the following property value in the IntroscopeAgent.profile to point to the absolute path for the .Net agent extensions

 

change

 

introscope.agent.extensions.directory=extensions

 

to

 

introscope.agent.extensions.directory=D:\CA APM\wily\extensions
