@burnout426 https://pastebin.com/HHWtHxcF for the full Install Status
It looks like there are two scheduled autoupdate tasks one for the user and one for program files installation. The one in Program Files includes C:\Program Files\Opera\autoupdate\opera_autoupdate.exe --scheduled-task --bypasslauncher $(Arg0)
The one for the user profile includes C:\Users\user.name\AppData\Local\Programs\Opera\autoupdate\opera_autoupdate.exe --scheduledtask --bypasslauncher $(Arg0)
Is it possible that the users themselves somehow ran another installer? or maybe selected an update prompt in opera that triggered it to do it's own thing?
