Re: ENS Installation Error mcafee ens the installer wizard was interrupted

Hi @avilt ,

As per the logs it looks like McAfee's own drivers were untrusted by McAfee installation process . This indicates that you are missing root certificate updates and MsgBusCert updates for McAfee Agent installed.

you need to :

1. Created a product update task to update the MsgBusCert for the McAfee Agent current installed in client.

2. Follow KB91697 to update root certificates.

3. Reboot the machine .

4. Make sure there is no trances of ENS install attempts left in registry and program files folder (If you see traces, use EPR tool and reboot the machine ).

5. Try installation / deployment. (Make sure to a compatible version of Trellix Agent installed ) 

If you still experience the same issue . I would advice to contact support.

You can also follow the below post to troubleshoot the issue :
