AacAmbientLighting.exe Issue

Hi, I'm not sure if this is an appropriate place to post this, please do let me know if not.

I have for the last two days been getting the following message popping up on my machine and I can't work out for what reason.  I updated my Internet Security during that time, so automatic thought was it was that preventing the files been read, but I've disabled the Internet Security and the error message still crops up

I have also uninstalled and reinstalled Armoury Crate, uninstalling it does take the error away, but that causes other issues and I use ROG hardware.  So I kind of need Armoury Crate to be functioning.

This is the error that I'm seeing:

When I try and install the .Net Runtime software it says that 'the specified account already exists' so I'm a littled confused as to what might be causing the issue and how I can resolve it and keep Armoury Crate on my machine.
