I'm trying to install the game Magicka thorugh steam. I installed most of the required libraries with wine 1.7.8. Then I switched to wine 1.5.18 to install other libraries: dotnet30 and dotnet35. I'm using PlayOnLinux 4.2.4 on Ubuntu 14.04.
The first time I installed dotnet30, it was smooth and error free. The other times (also this error appears when installing dotnet35, since dotnet35 installs it in the process) I get a report error window, then a window notifying me about the error. It says:
"The Program ServiceModelReg.exe has encountered a serious problem and needs to close. We are sorry for the inconvenience"
Edit: Altough I used wine version 1.5.18 in PoL, winetricks probably uses wine 1.7.22 (if that makes any difference) and maybe doesn't install prereqs like dotnet20,dotnet20sp1,dotnet20sp2 like PoL does.
