This is the error Minion is reporting in reguards to that AddOn...
Code:
<message>DeleteService (update) failed: java.nio.file.AccessDeniedException: C:\Users\Neerol\Documents\Elder Scrolls Online\live\AddOns\Zolan_ChatNotifications\.git\objects\04\c0777ee2ae02f302c296cb8a75c649ebe185ba</message>
Looks like Minion does not have permission to delete the .git folder that's inside that AddOn so that it can unzip the new version in this place.
I suggest manually deleteing the addon and re-installing.
