Since you have stated a Installation issue - Could you please let us know whether you have a trouble in installing McAfee application or is it some different issue ?
Sorry if I was not clear. This is not an installation issue. I have had the McAfee Internet security suite installed and running on my machine for a while now. Of late I keep getting the mentioned error popping up.
Like mentioned, it is very similar to the issue mentioned in https://community.mcafee.com/thread/30358
