--- Comment #5 from b.barwich@hotmail.com --- I am also running a Centos7 system on which I also have wine and winetricks installed.
$ wine --version wine-1.7.21 $ winetricks --version 20141130 - sha1sum: 7f03acb40d7fe3b6f3a1477ff936b3b17886e634
On that system I was unable to install dotnet20 because the Microsoft Installer failed during installation. But according to your first hint I tried to install dotnet35 that did install me dotnet20sp1 dotnet20 dotnet30sp1 Having those libraries installed I finally was able to run the Application.
On the first Debian8 system I tried to repeat the installation but winetricks would not install dotnet30 because it said it would conflict with dotnet20 and dotnet30sp1 would conflict with dotnet20sp1. But I managed to download the native .NET 3.0 installer and to run it with wine. After that I could run on the first system the Application as well
So I understand that the requisit for this Application is dotnet30
But after all I was unable to install dotnet35 or native .NET 3.5
Certain functionality does not work on wine with dotnet30. I hope that will fixed with dotnet35.
