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\ | 
If installation fails after adding all the above exceptions:
- 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
 
- Create another exception for this process.
 Or, exclude the following paths:- "%temp%\mfempt"*
- "%windir%\temp\mfempt"*
- "C:\Users\AppData\Local\Temp\mfempt**"
