Hello folks,

well one of the problems is that osu! is updated/rewritten with different .NET
Framework version targets and you recycle the same ticket from 7 years ago for
different problems.

22 captures of the web-installer over timeframe from 2014 to 2019

Using the latest snapshot from May 29, 2019:

Results in: "Error: please check your internet connection".

Confirming the issue with old bootstrapper from 2014, targeting .NET Framework
2.0.

'winetricks -q dotnet20' works around for the obfuscation problem. The
bootstrapper updates the client but is stuck in an update loop after restart ->
