Citavi 4 is built with .NET 4.5 which can't be run under wine yet.
According to Citavi Customer Service Preview 3 (=18.104.22.1682) will be the last Preview which will be superseded by a first Beta.
It will be installed with InstallShield which makes the workaround from V 3.x using the portable version unnecessary.
