When installing a McAfee agent on clients or servers when using McAfee EpO server, sometimes the McAfee agent icon dissapear. Mostly this simple execution will work to show the icon again:

c:\program files (x86)\mcafee\common framework\cmdagent

 

 

For Mcafee Agent version 5.x do this:

  1. Go to C:\program files (x86)\McAfee\Agent
  2. Run UpdaterUI.exe
