Troubleshooting Client Proxy Installation Issues

When you install Client Proxy with a third-party Endpoint Protection application, you might need to create exceptions in third-party applications (a third-party Endpoint Protection application might be from Broadcom or Sophos). The exceptions are to exclude Client Proxy from being filtered or inspected.

Installation Issues

When you install Client Proxy on a client with a third-party Endpoint Protection product already installed, your client experiences one or more of the following issues:

  • Client Proxy fails to install.
  • The Client Proxy service fails to start.
  • You can't configure Client Proxy to perform a redirect (you can't apply a policy to Client Proxy).
  • The client no longer has internet access.
  • Kernel Panics on macOS.
  • Client Proxy Services stop responding (hanging) and a major decrease in connectivity is seen (macOS).

Workaround 

To resolve this issue, create the following exceptions in your Endpoint Protection application to exclude Client Proxy from being filtered or inspected:

On Windows
Directories including subdirectories (depending on the third-party software you use, you might need to add * to the end of the path):

Client Proxy 4.4.x and earlier Client Proxy 4.5.x and later
%PROGRAM FILES%\Common Files\McAfee\SystemCore\
(usually C:\Program Files\Common Files\McAfee\SystemCore\)
%PROGRAM FILES%\Common Files\McAfee\SystemCore\
(usually C:\Program Files\Common Files\McAfee\SystemCore\)
C:\Program Files\McAfee\ C:\Program Files\Skyhigh\
C:\ProgramData\McAfee\ C:\ProgramData\Skyhigh\
Executables

/usr/local/McAfee/Scp/bin/scpd

/usr/local/McAfee/fmp/bin64/fmpd

/usr/local/McAfee/fmp/bin64/fmpd

If removal fails after adding all the above exceptions:

  1. Check if the VSCore framework has created the mfehidin.exe process in the \temp folder.
    For example: C:\Users\USERNAME\AppData\Local\Temp\mfempt17400029\mfehidin.exe
     
  2. Create another exception for this process.
    Or, exclude the following paths:
    • "%temp%\mfempt"*
    • "%windir%\temp\mfempt"* 
    • "C:\Users\AppData\Local\Temp\mfempt**"

All files and binaries of the below directory must be excluded in your other security products.
