Having read all of the above, do we go down the 'it's there so update it' route or hit the 'don't ever darken my door with this rubbish again' route :think: I don't like installing things I don't need and as I obviously don't have anything with .NET 3 (otherwise I'd already have it).. why bother :roll: TBH.. I don't know what uses the other 3 versions I have either
