Environment

 

  Web Agent 12.52SP1CR10 build 2813 on IIS 8.5 on Windows 2012R2;

 

Cause

 

There are 2 WebAgent.conf files (one in 64bit folder and the other in
32bit folder) which enables the Web Agent and starts each agent .dll. But
from the Application pool configuration, there is no classic 32bit
application.

 

Resolution

 

Set the WebAgent.conf for the 32bit library (32bit folder) to
disable this agent :

  EnableWebAgent="YES"
  to
  EnableWebAgent="NO"

or remove the 32bit WebAgent.conf to solve this issue.
