I'm really confused now.

Your suggestion that I launch Minion with Admin privileges seemed to work and it booted up and demanded that i let it scan for ESO and WoW. Which I did.

It found ESO (I don't play WoW) but it then told me I only had three addons loaded

Firkins Mini-Map - which i don;t actually use.
Skyshards
and Undiscovered.

All of which needed updates.

It looks as though it is looking in the wrong place for the ESOLive folder.

It says it's looking at: C:\Users\David Hatch\Documents\Elder Scrolls Online\liveeu\AddOns but I store all my user files on a separate drive. So there is no ESOLive folder on my C: drive at all.

However, I managed to work out how to redirect the path to the actual location of ESOLive on my PC and that seemed to sort the problem out.

So, I think everything is working now. thanks for your help.
