I'm thinking a hard reset is in order.
At first it would go through the process and say unsucessfull, but I would get the startup screen for the new version, then it started saying unsucessfull as soon as I clicked the cab. Either way when clicking "Launch Browser" from TF3d it would give me the "I'm sorry" WM screen.
It did always say that it could not remove the previous version of Opera, so maybe its just a stuck process somewhere.
It appears that I and another member have a similar problem
