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 a .dll. But
from the Application pool configuration, there's 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.
