We are running AppDynamics.Agent.Coordinator 4.2.8. When this service is running, we get this error.

Is this the same issue as referenced in : https://community.appdynamics.com/t5/NET-Agent-Installation/Could-not-load-file-or-assembly-Newtonso...
I looked at the release notes for 4.3.1, but did not see a resolved issue specifically for GAC access issues.
Solved! Go to Solution.
Can you try adding <add-assembly-reference enabled="false" /> section at your config.xml located at C:\ProgramData\AppDynamics\DotNetAgent\Config
Your config.xml will look like following ( content in bold needs to be added). Once you add this section please recycle Agent Coordinator Service and instrumented section
<add-assembly-reference enabled="false" />
Let us know if this does not resolve the issue.
